You got me curious and I just did a quick look at some of those airports, I excluded MSY due to New Orleans just due to it's popularity (notoriety?) compared to the other cities. I was surprised to see that Albuquerque had alot more movement that I would have guessed, between TUL, OKC and ABQ, Little Rock has by far the least PAX movement. I noted all 4 airports I looked at had a YTD decrease in PAX movement compared to 2014 and the couple of months of 2015 data I looked at saw a 5% decrease for OKC in SW movement for July and a 9% decrease for ABQ SW movement in June. Seems the Wright Amendment is affecting more than just LIT. Plane Movement As Architect pointed out I left off the most important airport! LIT has been added for comparison.
