I was kinda wondering about this kind of stuff... I was debating going without a bag of any kind since when I flew to Seattle I felt so liberated and free, it was a really weird experience. (Not having to lug something with me to the restroom, or worry about overhead space if I wasn't one of the first to board, or under the seat in front of me... Did you know econ seats on short hauls actually are pretty decent if you don't have any bags under the seat in front of you?! :P etc)

I was thinking even if I was stuck in PHL till the next morning to get out of there whats 24 hours in the same clothes? It's not hot and sweaty out, I didn't trek all over the city before hand, I was just sitting around all day. I like to think while not ideal I wouldn't have become "offensive" to those seated around me... If you catch my drift...

I don't know, it was just so enjoyable without any, and that was a short 50 min flight and a regional airport and SEA... I'll seriously considered the bag now though...
