TLDR
- American Airlines dismissed speculation about a potential merger with United Airlines (UAL)
- AAL shares declined more than 1% during after-hours trading after the announcement
- United’s CEO Scott Kirby allegedly proposed the merger concept to White House officials in February
- The combined entity would form the world’s biggest airline carrier
- Transportation Secretary Sean Duffy indicated consolidation could happen, but deals would undergo rigorous review
American Airlines issued a strong rebuke on Friday regarding speculation about a possible consolidation with United Airlines, causing its shares to retreat during extended trading hours.
AAL dropped more than 1% after-hours following the carrier’s public statement clarifying it has no involvement in, or desire for, merger discussions with United.
American Airlines Group Inc., AAL
“A merger with United would harm competition and disadvantage consumers,” American Airlines stated, further noting that such a transaction would contradict “our interpretation of the Administration’s stated principles.”
The firm denial followed a Bloomberg news story disclosing that United’s chief executive Scott Kirby had presented the merger proposal to high-ranking government leaders, including President Trump, during February.
Kirby previously held the position of President at American Airlines before transitioning to United, where he currently leads as CEO.
The Bloomberg reporting does not indicate whether any official exploratory discussions are currently taking place regarding a potential transaction.
Regulatory Hurdles Would Be Substantial
Combining AAL and UAL would result in the world’s largest airline operation.
The two companies collectively command over one-third of domestic U.S. passenger traffic, alongside competitors like Delta (DAL) and Southwest (LUV).
Industry observers have emphasized that a transaction of this magnitude would invite rigorous antitrust examination and probably encounter resistance from consumer advocacy organizations and competing airlines.
Transportation Secretary Sean Duffy commented on airline industry consolidation earlier this month during a CNBC interview, suggesting opportunities exist for mergers within the sector.
Duffy mentioned that President Trump generally favors large-scale corporate transactions.
Federal Review Would Remain Mandatory
Nevertheless, Duffy cautioned that any significant airline consolidation would undergo thorough evaluation regarding effects on airfare pricing and competitive dynamics.
He indicated that merging companies would probably be required to sell off certain operations if two major airlines joined forces, preventing unhealthy market dominance.
American Airlines’ public response seemed designed to acknowledge this regulatory landscape, characterizing a United combination as incompatible with antitrust standards.
UAL shares had risen 7.12% during the week, potentially driven by consolidation rumors, while AAL had appreciated 4.16% over the same timeframe before Friday’s after-hours decline.
As of 6:09 PM ET Friday, AAL had retreated as investors processed the airline’s unequivocal rejection of the proposed transaction.
