NW Arkansas airport also has a surprising amount of service for an airport in that location - American, Delta, and United regional affiliates. serve most of their hubs from there. Presumably a lot of this traffic is either Walmart corporate or suppliers that have located an office in Northwest Arkansas to be close to Walmart. I'm not saying that Amazon would pick a place like that - Walmart has always been in Arkansas. But air service will come if necessary. That makes me wonder about Pittsburgh and Raleigh-Durham, which both have underused airports (PIT as a former US Airways hub, RDU a former American hub).
