KCI to O'Hare, sat next to a drunk guy. He was drunk when he got on the plane, and had several more within the slightly less than hour flight time. He was pretty talkative to me (I was 13, alone on this flight). All the other people smiled at me cause I was the one keeping the drunk guy occupied.
PHL to KCI, sat in the middle seat, cousin was in the window seat, aisle seat was some huge guy. He needed a seatbelt extender. He sweat the entire time and breathed loud. This was tough to deal with, I was tired and wanted to sleep but couldn't lean back, or lean over, so had to just lean my head forward and try to sleep. I was also scrunched in pretty good so I couldn't move.
KCI to IND - Sat next to a lady who had a cat in a cat carrier under her seat. It meowed the entire time. Sucked.
