Hi,
This happened at all sorts of different times. First time was a flight to Geneva but on the return flight i was fine. Second was when i was flying a grob tutor and third time was flying to turkey but on the return flight i was fine
. I had done some flights in between those and i was fine too. I did have a cold on two of the occasions but when i flew to turkey i didn't think i had a cold until then lol.
Thanks for advice.
