flying at 32-33 weeks without hubby what are you thoughts?

Sadie
I'm booked to go on a hen do to Spain which is a two hour flight from the uk. I've had a really good pregnancy so far and just starting to get uncomfortable with the ever growing bump, I thought I'd feel ok about flying but I am concerned about risks and if it's possible to trigger early labour?! Have many of you mummies flown so late on??
