International Travel at 7 months

I traveled 6 hours at 8 months pregnant! Only thing is you will of course be more uncomfortable than usual but you should be okay

Just try choosing an aisle seat if possible just so you can take stand easier if you get too tired of sitting

Yes, I did. I would definitely clear it with your doctor first, my doctor told me not to go anywhere that I wouldn’t be comfortable having the baby and to be careful about what you eat in addition to the normal stay hydrated and move a lot on the plane.
You may not feel comfortable on the plane for that long. My last long flight was at 33 weeks and about four hours into the flight I was regretting the decision to go. How long will you be there? Are you able to change the dates?

I traveled that far along both by plane (only 4 hours) and shortly after by car (10 hours). I was recommended to wear compression socks and to get up and walk every two hours and to make sure to stay hydrated.

Remember those compression socks and to walk the aisles!
