Hey not really the same problem but close enough I figured id post on here. I currently am working on my Commercial multi and dont get nautious at all while flying. Sitting in the back is fine too until its in an airliner. I dont know why but i always feel quesy. I dont get it one bit it can be humid, hot and bumpy as heck but I dont get affected in planes im flying or backseating. The minute i get in an airliner I sometimes get nautious and I say sometimes cause its not everytime but id say lately 50/50. Any ideas?
