FAQs for booking flights from Austin to Buffalo

  • How can I fly from Austin (AUS) to Buffalo (BUF)?

    There aren’t any airlines with a direct connection from Austin to Buffalo. All trips will have at least one layover on the way, and the location is primarily dependent on the airline you’re flying with. For instance, when flying with Delta, the most likely layovers will be in Atlanta, Detroit, or New York - while American Airlines has Charlotte and Chicago as the most probable layovers.

  • Is it possible for my child to fly unaccompanied from Austin to Buffalo?

    It depends on how old the minor is. Kids below the age of seven cannot travel unaccompanied on this route because there aren’t any direct connections, and both American Airlines and Delta require the child to be at least 8 years old to travel alone on a connecting flight. If they pass the minimum age requirement, then you will have to pay for the unaccompanied minors' fee for them to travel alone. However, if they are well into their teenage years (15–17 years) the fee is only optional.

  • Which airlines have a lounge at Austin-Bergstrom International Airport (AUS)?

    American Airlines, Delta, and United Airlines all have one lounge each at AUS Airport. Both the United Club and American Airlines Admirals Club are located on the mezzanine level of the Barbara Jordan Terminal adjacent to Gate 22 while the Delta Sky Club is located near Gate 4. To access these lounges, you will have to book a first-class ticket with the respective airlines or buy a day pass at the door.

  • Delta Airlines offers free Wi-Fi to all passengers, even those seating in the Economy Class Cabin. This makes them a better option than American Airlines - who charge for the Wi-Fi, and United - which doesn’t have the service altogether.
  • American Airlines Economy class seats come with power outlets and a snack to enjoy during the flight from Austin to Buffalo. They are the only airline serving this route offering these amenities to economy class passengers.
