On March 3, 2025, American Airlines officially filed a petition for a writ of certiorari to the U.S. Supreme Court in order to have a First Circuit Court of Appeals decision reversed regarding its Northeast joint venture with JetBlue Airways.[1] In their petition, American Airlines argues that the First Circuit decision “invalidated a joint venture . . . that increased marketwide competition among all airlines in the congested Northeast without any price increases solely because it reduced competition between the two joint venture partners.”[2] They further argued the First Circuit’s holding “flouts basic antitrust principles, creates two circuit splits, and threatens to wreak havoc on productive collaborations of all shapes and sizes.”[3]
American Airlines’ petition comes as no surprise, since the joint venture between them and JetBlue Airways was announced in July 2020 and was later approved by the U.S. Transportation Department at the end of Trump’s first administration in January 2021.[4] Months later the Department of Justice, then under President Joe Biden, along with six states, filed suit in an effort to “unwind the deal” and argued the joint venture was a “de facto merger” that “remove[d] incentives for [the two airlines] to compete.”[5] The primary allegation was that the joint venture “violated section one of the Sherman Act, which prohibits ‘contract[s], combination[s] . . ., or [conspiracies], in restraint of trade or commerce.’”[6]
Under the Northeast Alliance (“NEA”) “the carriers effectively agreed to operate as a single airline with respect to most of their routes in and out of Boston and New York City.”[7] The optics surrounding the NEA were under suspicion, as American is “arguably the largest airline in the world and one of four airlines that collectively control[s] around eighty percent of domestic air travel,” while JetBlue is “the sixth largest airline in the U.S.”[8] Prior to entering into the NEA, American and JetBlue were leading competitors in the Northeast and would react to each other regarding “any fare or schedule change by the other carrier in the same market.”[9] With the active competition, both airlines were experiencing limits on access to gates, as well as limitations on their abilities to operate at the airports in the Northeast with the routes they could offer.[10]
This competition led American and JetBlue to enter into the NEA, as American had done a similar joint venture with Alaska Airlines on the West Coast that led to positive results.[11] The only difference between the two agreements was that American and Alaska were “not direct competitors prior to the WCIA, which instead was meant to leverage their complementary networks.”[12] However, in July 2020, the NEA was established, and it included “’codesharing, schedule coordination, revenue sharing, reciprocal loyalty benefits, and joint corporate customer benefits.”[13] In practice the NEA provided an opportunity for both airlines to “pool airport infrastructure, including slots and gates.”[14]
The DOJ’s lawsuit resulted in a month-long bench trial, which included “testimony by two dozen witnesses, most of whom were either executives of the defendants or experts paid for their testimony by one side or the other.”[15] The District Court, after digesting all the evidence, determined that the NEA violated the Sherman Act, and therefore was “PERMANENTLY ENJOINED.”[16] The injunction ordered both airlines to “cease all coordination of schedules, routes, or any effort to allocate markets,” as well as prohibiting them “from entering into any arrangement substantially similar to the NEA.”[17] The rationale behind the injunction was explained by Judge Sorokin, who stated that “[t]he NEA, operating as it was designed and intended by American and JetBlue, substantially diminishe[d] competition in the domestic market for air travel.”[18] Explaining further, Sorokin stated that American and JetBlue “replac[ed] full-throated competition with broad cooperation.”[19] After the injunction was entered JetBlue exited the NEA, which then left American as the only remaining defendant in the action.[20]
This decision by the district court was viewed as “a victory for President Joe Biden’s administration, [who had] taken a hard line on consolidation and tie-ups in the aviation industry.”[21] Merrick Garland, who was the U.S. Attorney General at the time, stated the decision was “a win for Americans who rely on competition between airlines to travel affordably.”[22] American then appealed to the United States Court of Appeals for the First Circuit.[23]
On appeal, American’s primary argument was that there was “legal error” in “the district court’s rule-of-reason analysis.”[24] Primarily, American argued that “joint ventures like the NEA are ‘not usually unlawful,’” so the district court “erroneously subjected the NEA to “quick look condemnation.”[25] The First Circuit Court of Appeals found American’s argument “unavailing on multiple levels.”[26] They started their analysis explaining that just because the NEA is a joint venture does not mean it is subjected to a different level of antitrust scrutiny or a different analysis, as the analysis of a joint venture is “aimed at substance rather than form.”[27] Looking further, the rule-of-reason analysis is a “’fact-specific assessment’ that varies based on ‘the circumstances, details, and logic of a restraint.’”[28]
In reaction to American’s claim that the district court took a “quick look,” the Court stated that the “NEA merited a less ‘deep and searching analysis,’” as the trial was a month long, which allowed the court to see the NEA’s effects on competition.[29]
The First Circuit Court of Appeals additionally disagreed with American’s argument “that the district court unlawfully treated the NEA’s empirical effects on output on price as immaterial.”[30] They had multiple reasons to disagree with American, since the NEA did have negative effects on the market, but primarily that American did not argue that there was error in the district court’s finding that the NEA “led to decreased capacity, lower frequencies, or reduced consumer choices on multiple routes, including some that are heavily traveled.”[31] Despite this, American continued to argue that the NEA resulted in “increased capacity in the form of ‘more flights, more seats, more routes, shorter connections, better frequent flyer benefits, and more choices.’”[32] The only issue with their contention was that the district court had “expressly rejected as unreliable” the evidence that American offered in support of their claims.[33]
The First Circuit Court of Appeals further backed up their support of the district court decision by explaining that the “NEA’s market allocation resides near the anticompetitive end of the spectrum” and that the district court decision “rests on stable footing.”[34] Overall, American lost on appeal, as the First Circuit explained that “an agreement between two powerful competitors sharing revenues and divvying up highly concentrated markets” is violative of the Sherman Act.[35]
With Trump back in office, American appealed to the U.S. Supreme Court in an effort to have the First Circuit decision reversed.[36] American’s primary argument is that the NEA was “designed to increase market-wide competition among all airlines” as well as “expand customer options in the Northeast.”[37] Since American is one of three “global network carriers” operating in the United States, along with Delta Airlines and United Airlines, their stated goal with the NEA was to create “a more formidable competitor in the region.”[38] It appears as if American is throwing a “hail mary” with the hopes that “the arrival of the Trump administration could set American’s petition up for more success.”[39]
Overall, what happens with American’s appeal to the U.S. Supreme Court remains to be seen, but if taken up by the Court their decision will demonstrate the effects of the Executive on appeals, as well as how the Department of Justice operates under different Presidents.
