Note:
BTS reports average fares based on a 10 percent sample of domestic itinerary fares. Domestic includes itineraries within or between the 50 U.S. States and the District of Columbia. Itinerary fares consist of round-trip fares, unless the customer does not purchase a return trip. In that case, BTS included the one-way fare. BTS based fares on the total ticket value, which consists of the price charged by the airlines plus any additional taxes and fees levied by an outside entity at the time of purchase. Fares include only the price paid at the time of the ticket purchase and do not include fees for optional services, such as baggage fees. Averages do not include frequent-flyer or “zero fares.”
