I wished I took picture. It lies flat on its back on the floor and the sides fit nicely in between metal parts of the seat in front. There’s also good clearence above the bag with the lower part of the seat in front. The only thing is the handles: they are not exactly in line with the back of the seat and poke out a little so I had to remind my husband not to step on them on his way outGood to know that for SQ Economy the B35 can fit under the seat without being squished!

Obviously there are lots of metal in that area so I made sure the bag including handles were fully covered. It survived
