.....i'll chime in too....same fears but dang it, there was stuff to do! more than 20 trips and never hit once in air or just after. carried imi or zomig and energy drink on plane just in case, oxygen at the destination usually through Lincare travel program. you adapt, clusterheads are good at that! get your well prepared first one out of the way....it gets less anxiety inducing every time after that......
