Travel on airplanes sucks now. My legs are cramped because i cant stretch them out, if i drop anything theres not enough room to bend and reach to pick it up, the trays if down crowd my middle, the pocket on the seat in front is so small i cant even put my water bottle in it, because the seats are so close, the recline function is pretty irrelevant, but the staff are great and doing their best.
