Flying with 2 airlines I'm 28-29 was pregnant. Both say they require a dr note from 28 weeks. I'm not sure how they would actually know but I don't dare risk it. My gp will do the note for £15. Airline says they need to see original, will they keep it - I.e. Do I need to get two copies at £15 each to get there and back? Flying with monarch and vueling.
