Those who feel like they really do need to recline their seats on a flight should feel free to do so. Post suggests going about it like this: "If this is really my back pain or if I'm bigger than the space that I am in and want some relief from that then I think it's turning around and saying, 'I'm going to recline my seat for a little bit to relieve my back and get a little bit of space. I'm going to set a timer for X amount of time, and I'll put it back up then. Please let me know if you need to move it to get out or anything.'"
