Connecting Alternatives

Via DFW (American), IAH (United), ATL (Delta), PHX (American/Southwest), DEN (United/Southwest). Adds 1.5–3 hours. Sometimes cheaper than non-stop.

For this transcontinental leisure route, Southwest's frequency and flexible policies (bags fly free, no change fees) often make it the default choice.
