I have spent a whole chunk of my life flying on all sorts of aircraft and the only one that makes me feel queasy is the 777.
I have had the strange sick feeling that many complain of and had nose bleeds (which, incidentaly, did not involve my finger) on several occasions.
If I get the feelings and am close enough I ask the drivers what they have just done and often it is a turn.
I know there have been studies on this but dont know if they came to a conclusion.
