Just talk to your ob or midwife before your trip. I flew from Denver to Tel Aviv at 6 months. I requested a roomier place on the plane for seating. We were there for 3 weeks and then Paris for a week. The only issue I had was that I got a cold. You can catch one going to the grocery store, so the travel wasn't what did it. Just get up and stretch as often as possible. I also carried a note from my ob that contained any necessary info like normal pg, blood type, twins, single, etc.
