Did not fit in between airplane seats.  We were traveling qatar which has more than normal leg space.
I bought 2 of these for my kids 8 and 5 when 8 was traveling alone with them across the Pacific on a 16 hour flight.  These didn't even fit in between the seat! Kids hated these and I had to first inflate by mouth and then deflate since kids didn't like these at all.  Ended returning this product.
