When my son and his partner flew to Texas last they flew Alaska that has only a couple of gates at Love Field in Dallas. That low number seems to come with lower prices in competition with Southwest. American and Delta airlines finally started flying out of there a few years ago (most moved to Dallas-Fort Worth Airport in the 1960s and never looked back). It was a territorial and legislative dispute that spanned decades. I don't like driving to Dallas' airport, but I like seeing my son, so I do it. :)
