Lately, I pay a bit more to fly AA as Southwest flights are always packed. Also, enjoy the pre-assigned seats.So many reasons why I'd be ok never having to fly again. Just being packed in way too close with people I don't know. A few years back, I had the middle seat between 2 very attractive young women. Had they known each other, I would have gladly switched seat with either, but that wasn't the case. While they were very pleasant, 3 hours of being packed in so tight felt incredibly awkward. After the flight I realized how much I've aged, how uncomfortable I am with people, and how much larger my personal bubble has become. That hasn't improved in the 10 years since.
The wife and I talk about on the rare occasions when we fly, we should save the extra money for 1st class just for that little bit of extra room.
