Seems like a bigger delay is the #$%^&* hub and spoke model. Not too long ago I could catch a direct light to many, many cities in Europe. Now, I need to fly into a hub first - often passing right over my final destination (then having unboard, reboard, and fly back, easily another 1-2h).

And don't even talk about the security theater. Sometimes twice (although that gotten better in that there isn't a 2nd check.)

And, yes, I noticed that pure flight times got longer, about an hour on transcontinental flight. All this time I thought I made that up, but at speeds mentioned in the article this is about right.
