One of the staff on board was very helpful with my bag when I couldn’t get it to fit under the seat & he put it up above for me. Though I was disappointed with the tiny space under the seat that the bag I usually travel with would not fit. I have a cpap & instead of carrying a separate bag for it I that can get forgotten, I consolidate it with my book, purse items, snacks, pillow, & sweater in one larger tote with wheels.
