Flying whilst heavily pregnant?

So on my husbands 30th birthday weekend I'll be 30 weeks pregnant and he really wanted a weekend break away to Amsterdam just the two of us but thinks I can't fly as il be 30 weeks. Anyway the airline will let me fly up to 32 weeks with a doctors note which I've got and I've went ahead and booked it as a surprise 😬 I cannot wait to see his face ! Anyway I'm a bit nervous about flying whilst pregnant as I've never done that before. The flight is only 1hr15mins what's ur thoughts?
