For me it's that the floor gets bitterly cold, so my feet do too. I hate these flying cigar tubes and avoid them at all cost but sometimes it's inevitable. I'm on one Saturday PHL-YYZ as there was no better option ex ATL that didn't depart at 0500 or arrive after I need to be there.

I was a little surprised that these penalty-box little Barbie Magic Fun Jets are still flying and haven't been on one in years. Hope mine has had its hair dryers replaced!
