Background on Key Players and Relevance

The recent fluctuations in US airline stocks on Wall Street are due to the Department of Transportation (DOT) threatening Mexico over flight restrictions. This situation has significant implications for airlines on both sides of the border, particularly Aeroméxico and Delta Air Lines.

Aeroméxico, Mexico’s second-largest airline, and Delta Air Lines have enjoyed antitrust immunity since 2015. This privilege allows them to coordinate routes and pricing, as well as share revenues and profits on joint venture flights between the two countries. However, this immunity is set to expire on October 25, as the DOT accuses Mexico of violating the 2015 Air Transport Agreement.

DOT’s Concerns and Actions

Sean Duffy, the US Transportation Secretary, has accused Mexico of not adhering to the 2015 Air Transport Agreement. He claims that Mexican practices, such as reducing airport slots at the Benito Juárez International Airport (AICM) in Mexico City and pressuring cargo airlines to move operations to the Felipe Ángeles International Airport (AIFA), have negatively affected US airlines.

Impact on Airline Stocks

On Monday, major US airlines experienced mixed stock performance following the DOT’s announcement:

  • American Airlines: Down 1.52% to $12.32
  • JetBlue: Down 1.13% to $4.36
  • Republic Airlines: Down 0.35% to $36.88
  • Delta Air Lines: Down 0.44% to $56.04

Meanwhile, Southwest Airlines and United Airlines saw gains:

  • Southwest: Up 0.93% to $38.85
  • United Airlines: Up 0.11% to $92.35
