United and JetBlue announced a new partnership called Blue Sky, allowing them to sell each other's seats and offer reciprocal loyalty benefits. JetBlue customers can earn United miles and vice versa, enjoying perks like priority boarding. The deal, awaiting regulatory approval, aims to enhance competition and offer more choices for travelers. While some aspects begin this fall, specific timing and financial details remain undisclosed. This collaboration avoids the flight coordination that led to antitrust issues in JetBlue's previous alliances.
