I fly a bit with work and told work that I would not fly in late pg so my last one was at 30 weeks while pg. My feet swelled and I couldn't get my shoes on and the tray didn't go down but everything else was okay and I now have a perfectly healthly baby. Oh, and just a tip to remember where you parked your car. I lost mine and there were 4 staff looking for it and they thought I was going to give birth in the carpark!
