Seems a very grey area indeed. Well she told GP today that she was flying and he didn't say not to fly.

I guess without a health professional advising you not to fly and willing to document it then you've had it with insurance anyway. Its annual travel insurance and all pre-existing are covered and notified.

Yep not ideal but then faced with the idea of not being able to reschedule or cancel and lose probably £1000 (flights plus car hire plus accom) what do you do?

I'd have to be bleeding out of my eyeballs to cough this one up! :-)
