Travelling at 7 months

Hi mummies! Have you travelled overseas at 7 months pregnant? I want to go on a baby moon in late January, but my gynae can only give me an answer during my next appt in early January. But by then I'm sure the flight tickets will be expensive 😔 what are the chances of me getting on a plane then? And were you feeling too heavy by then to be moving around? Thanks for your answers mummies!
