I think I would feel really lame walking onto a plane with a pillow that size, embroidered in pink!
It looks like it reduces you useable buttock space (can we cay buttock on FT?) and pushes you forward, limiting your knee space even more - I not the photo chops out his knees from the shot.
Anyone who flies long haul more than two or three times a year should be able to generate enough miles with FTs help, and a few jello purchases!
Suggest saving pennies or buying a Bose QC2 would be a better investment, and one you can use
