Code Share Agreement

LAST UPDATED: December 7, 2016

What You Should Know

A code share agreement is an arrangement where two or more airlines share the same flight. In these arrangements, a U.S. air carrier may sell a seat on a flight that is actually operated by a foreign air carrier under a different flight number or code. However, compliance with the Fly America Act is satisfied only when the ticket or documentation for an electronic ticket identifies the U.S. flag air carrier's designator code and flight number.

See the example below, where Delta Airlines has a code share agreement with Air France to Paris, France:

Compliant: Delta Airlines (DL) 8399, shown as DL8399 on the ticket, e-ticket, or boarding pass.

Non-Compliant: Air France (AF) 0337, shown as AF0337 on the ticket, e-ticket, or boarding pass.

Documentation Requirements

To satisfy regulatory agreements that a flight is FAA compliant under a code share agreement, travelers must retain documentation that confirms the U.S. flag air carrier's designator code and flight number. This information is located on the ticket, e-ticket, or boarding pass. The traveler is responsible for retaining the appropriate document as proof of compliance.

Below is a list of the U.S. Flag Air Carriers and their codes:

  • AirTran Airways (FL)
  • Alaska Airlines (AS)
  • American Airlines (AA)
  • Continental Airlines (CO)
  • Delta Airlines (DL)
