NEW YORK—American Airlines is retrofitting its Airbus A319 and A320 fleets with larger first class cabins, bigger overhead bins, power at every seat and updated interiors designed to match the look of its newest Boeing 787-9 and Airbus A321XLR aircraft. The program addresses a product gap that has widened as Delta Air Lines and United Airlines spent years upgrading their own narrowbody cabins.

The seat count changes tell the clearest story. On the A319, first class grows from eight seats to 12, and total capacity rises from 128 to 132. Economy stays flat at 120. On the A320, first class expands from 12 seats to 16, but economy shrinks from 138 to 134, holding total capacity at 150. American is carving out premium rows by modifying the rear galley and pushing lavatories farther back to free up cabin floor space.

The redesigned first class seat adds privacy wings, extra storage and two cocktail trays. Overhead bins are larger throughout both aircraft. Every seat, regardless of cabin, gets a power outlet. American said the aesthetic matches its newer long-haul jets, a deliberate move toward a consistent look across the fleet.

On Wi-Fi, American is promising free high-speed access for AAdvantage loyalty members across its narrowbody fleet. Starlink satellite Wi-Fi is scheduled to arrive on the A319 and A320 in 2027. That connectivity push tracks with what travelers increasingly treat as a baseline expectation on domestic routes.

The economy trade-off is real. Seat pitch is being reduced to make the first class expansion work, and the galley modifications cut into crew workspace. American will gain four first class seats per A320 at the cost of four economy seats—a deliberate bet that premium revenue per seat outweighs the lost coach fare.

United scrapped plans to expand first class from 12 to 16 seats on its A320s. American is pressing ahead where United stepped back, which puts additional pressure on American to execute cleanly on the cabin experience, not just the seat count.

The seatback screen question hangs over the retrofit. American has removed screens from much of its narrowbody fleet over the past several years, betting that passengers would use personal devices. On the legacy A319s that still carried screens, those screens are being pulled out as part of this retrofit. American is seriously considering bringing seatback screens back to its narrowbody fleet—a potential reversal of prior strategy that would close one of the most visible product gaps between American and its two main domestic rivals.

Delta has retained screens on much of its fleet and built a reputation for cabin consistency. United went further, making seatback screens a stated standard across its product and arguing that they produce a better, more uniform passenger experience. American's bring-your-own-device approach once looked like a cost-smart simplification; it now reads as a disadvantage when corporate travel buyers compare options.

The pressure is financial as well as operational. Delta and United have both posted stronger margin performance, driven in part by premium cabin revenue. Business travelers willing to pay for first class or premium economy have gravitated toward carriers that offer a more polished product. American's retrofit program is a direct response to that revenue gap.

For American Airlines Group—ticker AAL, which closed Monday at $10.50—the narrowbody fleet upgrade represents a multi-year capital commitment with a long payback horizon. The airline has not disclosed the per-aircraft retrofit cost or the total program price tag. The Starlink installation alone, scheduled for 2027, adds another capital layer on top of the interior work.

The stock trades well below its major rivals on most valuation metrics, reflecting investor skepticism about American's ability to close the product and margin gap. Delta trades at a meaningful premium on forward earnings. The retrofit program is the operational foundation American needs to justify a re-rating, but seatback screens, Starlink timelines and execution risk on the galley redesign all remain open items between now and that outcome.
