American Airlines (AA, Dallas/Fort Worth) is planning to concentrate its growth at Dallas/Fort Worth and Charlotte International as gate access at these two hubs is much less expensive than at the carrier's other gateways, President Robert Isom has told analysts.

"With DFW and Charlotte, we’ve got tremendous ability with really cheap gates that are going to fit very well with the kind of capacity - when and if we add going out into the future," Isom has been quoted as saying by The Dallas Morning Herald.

In April, the carrier announced it would invest USD20 million into converting nine gates for narrowbody jets in its Terminal E at Dallas/Fort Worth into fifteen gates for regional aircraft. In Charlotte, the carrier is set to receive additional seven gates in Autumn 2019 after the expansion of the airport is completed.

The carrier has said that the financial results of services out of Dallas/Fort Worth and Charlotte, already its two largest hubs, are also better than at other gateways.

"It really outpaces what we do at a system average. That’s a good indication ultimately that anything we put in - in the right manner - is going to be effective for us," Isom has said, adding that the airline will remain "prudent" with growth pace.

According to the ch-aviation capacity module, American Airlines currently proffers 646,902 weekly seats out of Dallas/Fort Worth and 497,499 out of Charlotte, operating 5,080 and 4,531 weekly departures, respectively. This is significantly more than out of its third-largest hub, Chicago O'Hare, where AA offers 3,156 weekly departures and 337,906 weekly seats.

In addition, the carrier faces relatively little competition at those two hubs as it has an 82.6% market share by capacity at Dallas/Fort Worth and 90.7% at Charlotte, the ch-aviation capacity module shows.

The carrier also bases its aircraft out of Los Angeles International, Miami International, New York JFK, New York La Guardia, Philadelphia International, Phoenix Sky Harbor, St. Louis Lambert International, Washington Dulles, and Washington National.
