big airports in USA are one big mess & that's being kind.
No one wants to go to some big ugly airport just to get a plane. Most are like major shopping centres, except everything is very VERY expensive.
Moxy in USA will clean up along with LCCs that fly into smaller 2ndary airports, with quick in & out.
I along with millions of other frequent flyers, don't want to spend a minute longer at an airport that I have to.
Low costs don't want to go anywhere near big congested airports, with massive delays & passengers don't want to pay their outrageous car parking fees.
Also who wants to go to a hub airport ?
