Air discounts vary by airline, destination and fare type. It is the responsibility of the traveler to obtain the most economical airfare available consistent with the purpose of the trip. Whenever possible, travelers should take advantage of discounts and purchase airline tickets in advance. Non-refundable tickets provide the highest savings opportunities. While these tickets are a great way to save money, please make sure you know and understand the restrictions associated with them. If there is a good chance your itinerary will change, you need to weigh the savings against the change fees and restrictions that may apply if you change your ticket.
Note: On federally funded projects, the Fly America Act takes precedence over a less expensive foreign carrier.
