I was on a redeye from SFO-DFW-RDU. If you've never flown a west to east redeye, take my word for it that this is the worst one as you get off the plane in Dallas at 2:30 or 3:00am Pacific time. When I get to DFW, I'm exhausted and debating whether or not to shell out for the DFW-RDU upgrade because I'm fresh out of stickers (500-mile upgrade credits). I decide I'm really just too tired to care, and I'm going home to visit my family so I'll blow the $90. I snag the last F seat and settle in. A young boy comes down the aisle, probably 8 or so, stops, and looks at me. Then he throws up on the floor next to my seat and walks nonchalantly back into Y. A flight attendant lays a towel on top of the vomit, but doesn't halt the boarding. A minute later a little old asian lady boards with her rolling suitcase and, not noticing the towel, snags it on a wheel and drags it all down the aisle.
