Hi Yvette, I flew at 36 weeks from UK to Brisbane and although it was not fun, it was neccasary (DH wass in Oz I was in Eng!). Just make sure you walk around every hour to stop DVT and definatly don't drink!!! Also you may need a letter from your Dr stating your due date and that you are safe to fly. If your airline doesn't require one I would still get one anyway.

Have a safe trip
