The gate agent in Chicago took it upon himself to change my seat from a center seat to an aisle. Made me smile. It’s the little things like this that go a long way. These airlines that are selling every aspect and convenience of flying need to stop nickel and diming everything about the experience. Build a flat rate, many would be happy to pay. Upfront costs, let me check a bag, let me carryon a bag, give me a whole can of soda.
Don’t understand why my wife and I couldn’t sit together either leg, when there were single travelers next to each of us. Even though we were “basic economy” class, it seems like a little effort would have helped us. Thank you.
My flight was delayed due to mechanical, thus missing my connection. But Duluth personnel organized a new flight connection very efficiently.
Excellent flight Terrific pilot
Staff is awesome .. but please give me 2 extra inches in knees.. my knees kept hitting the seat in front
WILL THERE EVER be a time when senior citizens can get onto the plane first? In otherwords, can people over 65 board in the 3rd group - or people over 70, can they board in the 3rd group?

outdoor staff at the airport, need to learn how to use their badges to stop so much unnecessary buzzing at Phil airport. The noise was very high pitch and was going off frequently.
Baggage took too long in Philadelphia.
I was given an emergency exit seat.
Baggage claim was very slow
