Critics Raise Red Flags
1. Sen. Blumenthal’s Antitrust Alarm
Sen. Richard Blumenthal (D–CT) has written to the CEOs of both airlines, warning that the alliance “may harm full and fair competition and lead to fewer and more expensive options,” particularly in New York The Wall Street Journal+15Reuters+15CNBC+15.
2. Spirit Airlines Files Opposition
Spirit, a low-cost competitor, urged the U.S. Transportation Department to reject the deal, fearing JetBlue would become a “de facto vassal” of United—effectively neutralizing one of the few remaining low-fare challengers Flight Global+4Reuters+4AviationSource News+4.
3. Antitrust Precedent: Northeast Alliance Collapse
Back in 2023, a federal court struck down JetBlue’s Northeast Alliance with American Airlines after finding it driven up fares and suppressed competition in the Northeast U.S. CNBC+1Aviation.Direct+1. The Supreme Court declined to reinstate that partnership this past June CNBC.
Spirit argues Blue Sky presents similar risks: tacit coordination, diminished network independence, and inflated redemption costs—putting budget-conscious consumers at a disadvantage MarketWatch+5Aviation.Direct+5Financial Times+5.
Airlines Push Back
United and JetBlue defend the pact, asserting it preserves JetBlue’s operational independence and enhances competitiveness. They highlight that there is no schedule or pricing coordination, and that each airline will continue to market flights under its own brand Politico+11Reuters+11Reuters+11.
United CEO Scott Kirby emphasized JetBlue is an exception among low-cost carriers, calling Blue Sky “customer-focused” despite previous criticism of the ultra-low-cost model MarketWatch.
