I have tried flying in diapers several times. I know I've tried a tena slip maxi, ATN, and molicare, maybe some others. I don't remember ever being in one that didn't get a little uncomfortable due to wadding up or whatnot, after awhile of sitting fairly stationary for a long time. Unfortunately, the only ones I know of that don't cause that problem are too bulky to wear in an airport for me. Anybody have any suggestions for or experiences with a good diaper to mitigate this problem on long flights?
