Southwest Airlines added LOT Polish to its international partner airline to its network joining 10 others, but you can’t book them via Southwest.
The partner page on Southwest’s website, states: “Customers can book partner itineraries on each of our partners’ websites and channels. Eventually, we will also offer booking on Southwest.com®.” The Memorandum of Understanding between Icealandair, Southwest’s first international partner in recent years (Volaris and WestJet were former partners) was signed in September of 2024, and “went live” in February of 2025. But not online and not over the phone.
I also typed in the airport code of every partner hub city to be sure.
A great solo travel tip spotted this week on Live and Let's Fly.
