American Airlines' growth at Austin has been phenomenal. With 38 routes from the Texas capital this winter, including Albuquerque and Aspen, the carrier has been primarily responsible for the Texas capital's fast expansion.

Huge Austin growth

Austin is the USA's third fastest-growing airport. More than 1.5 million seats (+18%) have been added versus winter 2019 (W19), behind only Miami and Dallas. While Aeromexico, Alaska, Allegiant, Delta,  and Southwest have more capacity than they previously did, it has mainly been driven by American.

In W19, American had just under 1.5 million Austin seats across eight routes. As you'd expect, they were primarily hub routes to Charlotte, Chicago O'Hare, Dallas Fort Worth, Los Angeles, New York JFK, Philadelphia, and Phoenix, along with Las Vegas.

How things change. In W21, American's seats have virtually doubled to 2.9 million across 38 routes. The carrier's share of seats has risen from 17% in W19 to 29% this winter, analyzing OAG data confirms. While Southwest has also grown its Austin offering, the gap between the pair has narrowed.

American's flights have risen even faster

While American's Austin seats are up by 95%, flights are have grown by 117%. Driving this is the significant growth of American Eagle's 76-seat Embraer 175s, which have 12 seats in first, 20 in main cabin extra, and 44 in regular economy.

In W19, Eagle's E175s had 398 Austin flights; now, they have 6,992. Nonetheless, the B737-800 remains top and not just because of higher-density hub routes. Some 20 routes will see the narrowbody, including Boston, Cancun, Liberia, Nassau, Punta Cana, Puerto Vallarta, and Washington Dulles. Philadelphia also will on Thanksgiving, replacing the normal E175.

Going to the Texas capital, AA3903 will depart Albuquerque at 11:10 and arrive at 14:00. American will compete head-to-head with Southwest (also seven-weekly) and Allegiant (twice-weekly) from March 4th. The E175 will be used.
