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.

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)

There are only four Open Skies Agreements that have been determined to meet Fly America Act compliance requirements by the U.S. Department of Transportation.

These agreements represent the biggest exceptions to the Fly America Act because they allow use of foreign air carriers that provide services under a bilateral or multilateral air transportation agreement to which the United States Government and the government of a foreign country are parties.

Below are the four Open Skies Agreements in effect. Select a destination for important requirements about each agreement.

Open Skies Agreement U.S. & European Union (EU) including Norway and Iceland

• EU Member Countries

Open Skies Agreement U.S. & Australia

Open Skies Agreement U.S. & Japan

Open Skies Agreement U.S. & Switzerland

Important Notes:

1. Open Skies Agreements do not apply if travel is funded by the Department of Defense (DOD), including the U.S. Military (Army, Navy, and Air Force).

2. Travel under certain Open Skies Agreements can be restricted if a City Pair rate is in effect for the specified travel route. If a City Pair rate is in effect, then travel must be provided by a U.S.-flag air carrier, unless another authorized exception applies.

• No U.S.-flag air carrier provides service on a particular leg of the route

• A U.S.-flag air carrier involuntarily reroutes your travel on a foreign air carrier

• Use of the U.S.-flag air carrier would at least double your en-route travel time

• Use of a foreign air carrier is necessary for medical or safety reasons

• When traveler cannot purchase a ticket in the authorized class of service on a U.S.-flag air carrier, but a seat is available in the authorized class on a foreign air carrier
