Do you use a pillow to sleep on planes? I usually sleep on my stomach and this blow up pillow is the only way I have found to comfortably sleep on long haul flights. I have not had an issue with it on any airlines, though I know Korean airlines isn’t a fan of them. Yes I get weird looks when I blow it up but that about it. I once again had a middle seat on a long haul and was thrilled I brought it. Getting past the awkward use stage is hard but can be done
