How to fly when pregnant

As a bit of a jet setter with all my work travels, I have written in the past about the effects of flying and jet lag on infertility….but now I am 31 weeks pregnant I wondered what are the effects of flying whilst pregnant?

I don’t have lots of facts for you on this blog post, I know – unlike me!  However, I can tell you that the general advice is not to fly after 37 weeks or 32 weeks if you are carrying multiples.  Every airline has different rules about letting pregnant women fly, so check before you book your ticket!

Just because it is OK to fly before 37 weeks, this doesn’t mean that you won’t suffer side effects of flying when pregnant!!  Overall you are likely to experience leg swelling, bloody nose, ear problems and motion sickness will probably make any pregnancy related nausea worse.  Deep Vein Thrombosis is a higher risk if you fly when pregnant.

Here I offer you the effects that I have personally experienced and some lessons I’ve learned along the way.

So far, I have taken three transatlantic trips in my first trimester, two in my second trimester and two in my third trimester. Two of these trips in the first trimester have required me to make two connections – that’s three legs of flying!!! These trips were quite intense on my body and took a lot of energy out of me.  But overall, I survived them all!  I would like to say that I got used to flying when pregnant, but unfortunately as I get closer to my due date, it becomes more uncomfortable and I discover new challenges!

Picking the right seat in advance.  Choose your airline carefully!  Check out the average legroom by airline here at these two websites: US Airlines overview & All airlines at  Even before I was pregnant I would choose an aisle seat because of my terribly weak bladder and Irritable Bowels….but this has never been so important when pregnant.  Even when I was 6 weeks pregnant, I went to the toilet over 20 times on a 7 hour flight.  It was ridiculous!  I use the Seat Guru app to check in advance where the seat is in comparison to the toilets.  I like to choose to sit about 4 rows or so from the toilet – not so close you get the smell, noise and annoying people bumping you, but close enough to make a dash for it when it is empty!!

Upgrade if you can afford it.  Sounds obvious!  I have tried to upgrade on the red eye (overnight flight) a few times, but have failed to succeed!  Last time I was 5th on the list, and all 4 people in front of me got upgraded!! I was gutted.  Showing off a big bump doesn’t help unfortunately.  I had even saved up lots of my air miles just for this purpose knowing I’d pregnant at some point in the future!!  I don’t have several thousands of dollars to just buy a business class seat, so I’ve stuck it out in economy for all my flights.

Drinking and Feeding yourself.  Carry an empty plastic water bottle whenever possible to keep hydrated, particularly if you get stuck on the plane before takeoff or taxing after landing, it might be almost two hours by the time you get your next drink!

Fill up your carry-on bag with snacks for both journeys.  I also learned that it’s important to keep snacks for the return journey too just in case you are departing a foreign airport and the shops aren’t open, or certain foods make you nauseous.

I made the mistake of relying on the lunch given out on the plane…they cooked a pasta in a tomato herby sauce and before I even got the food I felt sick from the smell of the herby sauce.  That was the only choice, so I went hungry as I tried to force it down me, it just wasn’t happening!  I also slept straight through an entire meal service because of my tiredness so missed out on food, by the time I got off the plane, got through customs and security again for my next flight, I hadn’t eaten for 7 hours.  I was feeling so, so sick.  I didn’t just have the hun-grumps I was feeling light headed and dizzy.  Fortunately I had water with me at the least.

And another tip – don’t carry nuts, seeds, fruit or dried fruit otherwise it is likely you will have to declare them to customs when you land in another country– and ain’t nobody got time for that!

Getting in the Sleep.  In my first trimester I was suffering a lot from pregnancy tiredness, add on a 5,6 or even 7 hour time zone difference and I am screwed.  For my trip to Turkey I travelled through 4 different time zones.  I strongly suggest not trying to follow a routine, rather listen to your body and sleep when you can.  This is not easy to do.  I had to be at work at certain times and so that meant waking up in the middle of my sleep cycle…I was permanently tired and yawning throughout the day.  Fortunately, most people knew about my pregnancy very early on so they didn’t take it personally as I yawned through their briefs!!!

Remembering your Medication.  This was a nightmare.  I got it wrong big time with my second trip.  My first trip I did the progesterone in oil intra-muscular injections and administered them myself.  It was challenging and I hated it, but in terms of timing this one was easy.  Do the injection just before going to bed.  It didn’t matter about the time zone change because the progesterone lasts several hours longer than 24 hours, so it didn’t matter.  However, this time around after struggling with giving myself the injections, I took the progesterone capsule suppositories, 3 times a day.  This was really hard to do, especially with a 7 hour time zone difference.  I think the first day I travelled I took too much, then on my second day and third day I forgot to take my second suppository in the middle of the day because I was so busy with work.  Then I forgot to change my estrogen patches I was supposed to do on the red eye flight to Turkey.  I remembered the afternoon that I arrived in Turkey when I got into the shower.  So I would suggest putting reminders in a phone with the exact timings so as not to forget.

Don’t forget the sick bags.  Have one of those airline paper bags in your bag just in case you are in a queue and you can’t hold it in!  Fortunately, it didn’t happen to me, but there were times when I panicked I might puke and couldn’t make it to a toilet in time!!!!!

Coping with strange smells.  On one flight I was sat near a man who had a bad Bodily Odour problem.  I was trying not to vomit in my seat, hoping I would just get used to the smell for my 8 hour flight.  Fortunately, he moved two rows forward and my sensitive nose was saved!  But I have experienced smells of things I can’t bear with people sat next to me and then generally in foreign countries the smells are just different.  This is something I don’t know how to resolve or overcome.  It’s just one of those things I guess I’ve got to suck up.  Sorry I don’t have any ideas of how to cope with this, it is more of a warning!  Do you have any ideas??!

The swelling and back aches.  Later into my second and third trimesters I noticed that when I got off the plane the veins in my arms were massively swollen!  At first I was terrified, I looked like a freak and worried they were going to burst or a sign of something bad!  But I discovered later that this is to be expected when flying when pregnant.  There is also no avoiding crappy airline seats – I pack a spare feather pillow, fleecy blanket and neck pillow to make my seat more comfortable.  I have also treated myself to a maternity massage where I had 60 minutes of pure bliss focusing mostly on my lower back.  I have discovered in my third trimester that the lower back has quite a lot of tiny muscles I never knew existed!!

Get yourself Global Entry.  I successfully applied for global entry half way through my pregnancy – this enables you to use the automated passport border control as a ‘trusted traveller’.  The reason I got this was because one time I arrived into Chicago and queued for 2hrs to get through border control…I was feeling very faint by the end.  Nope.  I decided I am not doing that again, particularly for much later on in the pregnancy! I almost punched the woman behind me in the queue because she obviously came from a country where there was no such thing as personal space.  I think the hormones didn’t help me with my patience! So I applied and got a conditional approval after two weeks of applying – then had to wait three months for an available interview slot time that I could get to.  This interview was really quick and easy, it wasn’t so much as an interview for me, more of simply provide my finger prints and have a photo taken.

The other good thing about Global entry is that it also gives you TSA pre-check which is really nice…getting your shoes on and off in the third trimester is a pain in the butt so this has been a nice luxury!!! In my first trimester I travelled to Turkey, and as a result for four trips after I must have been put on a ‘list’ and got ‘extra screening’, known as the dreaded SSSS that gets printed on your boarding pass.  If you ever see this on your boarding pass – it is the ‘not so secret code’ that you will get extra screening.  All this means is that I got a thorough search of my bags, swabbed for explosives and a good pat down.  As long as you don’t fuss about it, the security agents are pretty good about it.

Take it easy and take a taxi.  I learned the hard way that a taxi is a must!  I am usually good and whenever I can get public transport I do.  I personally think it’s a lazy expense that some of my colleagues take.  So for my first trip I took the train and walked to the hotel for 15 mins.  However, this was actually a bad idea.  It was warm and I was dressed for the cold airplane, I almost passed out on my walk to the hotel!  Then lifting and carrying bags up and down stairs when there are no lifts is equally dumb (especially when I had my poor hyper-stimulated ovaries being tender still!).

Know who to call when things aren’t right.  Have a list of phone numbers you can call in case of an emergency, get info on doctors & hospital numbers/names/addresses for where you are going before departing. Fortunately, I’ve not needed this (although I learned this lesson more recently with my experience during the Brussels attacks and the importance of having emergency contacts ready to go and not stored on your phone!).

Not for everyone – telling people you are pregnant.  I know that many people do not like to tell others before the end of the first trimester about their pregnancy, I absolutely get that.  But for me on these work trips it has been really helpful.  I don’t feel guilty for running out of the room to the toilets when I need to, I don’t need to explain the yawning, I don’t need to explain why I am not drinking alcohol when everyone else does, generally I have felt comfortable overall because I have told people I am pregnant.  I don’t need to make excuses or justify my actions or wonder if people are guessing I am pregnant!

So that’s all my thoughts!  There are also some things that Baby Science Project suggested to me from her extensive work travels during her pregnancy…such as flight socks and baby aspirin.  I never used these…mostly because I haven’t been able to find any socks that aren’t horribly itchy.

My OB said I am OK to keep flying up to 34 weeks, assuming I pass all my checkups!  Although it is not top of my list to do when pregnant, it actually hasn’t been quite as bad as I thought.  It is definitely true that the first and third trimesters are the worst for travelling.  In the first trimester it’s the nausea.  In the third trimester, it is just uncomfortable and difficult to move around.  But….I survived to tell the tale.

    I have two questions for you..
    I have my blastocyst transfer day after tomorrow, i just wanted to know

    How much and to what extent do i need to take rest after transfer, can i climb stairs or move around?

    After 14 days i have my flight (6 hrs) , is it safe to travel if the result is positive?

      Ohhhh Good luck with your transfer!! That is very exciting news 🙂 Personally, I didn’t do yoga or play dodgeball after I transferred my embies although I didn’t exactly stay still for long!!; but there is much conflicting guidance out there about whether or not it is a good thing to get the blood getting good flow to the uterus by moving around!

      I had a similar conundrum to you a while ago – flying when PUPO and the flying effects on fertility overall, so I did some research, but couldn’t find anything very conclusive about early stages of pregnancy. I found some research that suggests that flight attendants have a small increased risk of miscarriage in comparison to women who don’t fly regularly – BUT correlation doesn’t equal causation, and there could be many other factors such as the fact that these guys are on their feet all day and have quite stressful jobs might increase their risk a little more.
      However, without any compelling evidence I personally believe it is safe to fly, by that point your embryo(s) will be snuggled down nicely 🙂

      Wishing you lots of luck for a smooth transfer!!!

      9 hours is the longest sat on a plane, but 26 hours of travelling has been my longest trip so far! I get soooo restless anyway…I’d hope that if you were to go home the plane you would be taking would have a little more leg room than the crappy American Airlines ones!!! Doc said to me yesterday that getting up and moving every hour is very important not necessarily length of flight that matters!

      Good luck for the start of your cycle BTW, I’ll be following and cheering for you 🙂

      We lived in southern africa during my pregnancy and went to a wedding in hawaii. that was 40h of travel and I was 18 weeks pregnant. I vomited a lot, slept a lot, walked when I could and stretched in my seat and enjoyed the good moments in between. My doctor in SA gave me lovenox shots for the flights to avoid risk of blood clots, which I really appreciated. I also used compression socks. I found that when I was feeling faint and people found out why I was always moved up to the front of the cue and given the best seats they could find for me at check in. In fact on our last flight, a woman gave me her seat which meant I had a whole row to myself while she sat with my husband so I could sleep. Bliss.

      No worries! Have a safe trip – I think it gets a bit more worriesome getting closer to EDD…I’m flying again on Saturday back to Europe, returning a week later -this will be my last trip of the pregnancy. I saw the doc yesterday and she checked my cervix just to be sure, that made me feel a bit more comfortable about flying at 32-33 weeks 🙂 Also my husband was getting a bit concerned too, so to get the doctor’s approval was important for him!!!

    Informative as always! And exactly what I would have said plus a bit more (I flew long haul once in my 26th week). I checked seat guru too and I echo everything you said re tips about hydration and so on.

    Another thing I would say, and this was just me and my bad timing, was don’t have the shots (flu and whooping cough) the day before you fly! I had a bad reaction to them so it wasn’t much fun at all and my arms ached really badly the first day and then still fairly painful for two days after that. Not ideal when pulling luggage along!

    And also I would say don’t think you can do what you did before pregnancy during pregnancy. I’ve had a few moments lately where I thought I’d be fine walking up stairs / wheeling luggage to and from hotel/work and just generally things which I wouldn’t think twice about normally, and I found that it took twice as long! I’m not as mobile as I used to be, but hadn’t quite got my head around it!

    For flying, the UK airlines seemed to say that it’s fine to fly before 28 weeks with no questions asked, but after that they would require a doctor’s note certifying you okay to fly. I think it depends on your doctor but apparently I’m considered “high risk” even though I haven’t had any problems really during the pregnancy, so they did imply it wasn’t advised for me to fly later than that.

      Oooooh yes I forgot about the part about ‘dont think you can do what you did before pregnancy during pregnancy.’. I am in fact ALWAYS forgetting this. I hate asking for help, but most people have just spotted me needing help with bags and given it without even saying a word! And getting lifts/elevators everywhere too!!! You are very right…even getting ready and dressed in the morning takes longer!!! Putting tights on for example is quite an ordeal now!!!!

      And this morning I was talking about the 28 week thing with a colleague whose wife tried to fly back to the UK on Virgin Atlantic and they wanted a note to say what her EDD was and certification of fit to fly. She had a note, but forgot to pack it!!! Luckily their neighbour managed to get into their house and take a picture of the letter for them and Virgin accepted this!!!!

        Haha! Yes I really didn’t factor in all the extra time to do the pregnant waddle (with heavy breathing) compared to my usual speed walking! I’m so not used to that. And I can relate to the tights thing too, haha! I ventured out without the belly band the other day, just tights, and they kept falling down. So my top tip for tights is to wear a belly band over the top (under clothes!) to hold them up! 😂

    You are such a trooper! We flew to Montreal to visit my in-laws when I was 13 weeks and I was so uncomfortable. I didn’t think it’d be that bad just at the start of the second trimester but I couldn’t seem to get comfy in the seat, my hips ached (fortunately I had an aisle seat for going to the washroom). I did wear flight socks because my doctor said I should but they were uncomfortable too. And that was only a 4-4.5 hour flight, gosh.

    I know exactly what you mean about the smells, there was a cashier at the grocery store the other day who had bad BO and the nausea was instant! The only thing I’ve been able to do that helps is to eat Tic Tacs because the powerful mint smell/taste fills my nose for a brief time. I’d say putting essential oils on a cotton ball in your purse or something, but for me that’d just give me a headache right now. I’ve had to swear off all perfumes for the duration. Anyway, respect for all the flying you do, I hope your additional trips will be uneventful and as comfortable as possible. These are great tips. 😀
