Just 70 Nautical Miles: Introducing Southwest Airlines’ New 2nd Short Route

Three of them stand out for being particularly short: Milwaukee-Chicago Midway, Knoxville-Nashville, and Tucson-Phoenix. They exist more or less entirely for transit traffic over what are among the evolving carrier’s busiest hubs-not-hubs.
