A flight must be economy-class on an American carrier in order to adhere to the Fly America Act. STEP cannot reimburse for extra leg-room or Business, First-Class airfares. Flight receipts must show the name of the traveler, the flight class, the dates/cities of travel, and the airline. If booking is done through a 3rd party service (like Expedia or Travelocity), the company is taking a risk that the carrier may be switched to a non-compliant airline without notice. One exception to this requirement is transportation provided under a bilateral or multilateral air transport agreement, to which the U.S. government and the government of a foreign country are parties, and which the Department of Transportation has determined meets the requirements of the Fly America Act. Please review the Fly America Act for further detail.
