United Airlines and JetBlue are teaming up in a new partnership called Blue Sky, which includes new loyalty benefits for MileagePlus and TrueBlue.

At the IATA AGM on Monday, JetBlue CEO Joanna Geraghty helped unpack what this deal actually is, and what it definitely is not.

With this alliance, you'll be able to use your points across both airlines and book flights on either's website or app.
