New York, February 27, 2026, 06:35 ET — Premarket
- AAL slipped at the open, pulling back after posting solid gains in the previous session.
- Capex and growth remain top of mind in Miami’s airport expansion plan.
- Washington keeps the pressure on airlines over reliability and consumer protections.
Shares of American Airlines Group Inc (AAL.O) slipped 1.1% to $13.79 ahead of Friday’s open, giving back a portion of gains from the previous session. The move comes after the airline unveiled an ambitious expansion blueprint for its Miami hub. 1
The Miami build-out is drawing attention to U.S. carriers’ ongoing challenge: adding capacity without tripping into the kinds of operational messes that can wipe out a week’s gains in just hours. For American, the project is another proving ground—will hefty infrastructure bets actually pay off in fewer delays and an improved experience as the airline ramps up for the busy summer?
There’s fresh attention from Washington, too. Deputy White House Chief of Staff James Blair posted on X that he’d be watching the airline industry more closely after both his and his wife’s American flights faced issues, according to Reuters. OAG’s aviation data cited in the same report showed American came in behind Southwest, United, and Delta for on-time arrivals in January, and also led the pack in cancellations. This comes as the Transportation Department is looking to scale back certain Biden-era consumer protections. 2
American finished Thursday up 4.65% at $13.94, leading gains among big U.S. carriers as equities turned in a mixed session. Delta added 1.90%, United picked up 3.15%. The S&P 500 slipped 0.54%, according to MarketWatch data. 3
American plans to put $1 billion into revamping Concourse D at Miami International Airport, aiming to add 17 new gates that can handle bigger planes and move passenger boarding inside. “Miami is an essential hub and international gateway,” CEO Robert Isom said. The airline operates roughly 400 flights a day out of Miami, accounting for over 60% of the airport’s total traffic. 4
Travel Weekly reports the overhaul will scrap the existing D60 layout—right now, it’s a single boarding door leading out to 17 gates at tarmac level. In its place: 17 standard gates, each one getting its own waiting area and sized up for bigger jets. Construction is set to kick off next year, wrapping by 2030, with improvements to dining, retail, and baggage handling in the mix. 5
Premarket moves tend to be choppy, with light volumes, and airlines are never far from the next flare-up—bad weather, crew shortages, airport bottlenecks. Major terminal upgrades don’t escape the hazards either: delays, escalating costs, or politics that turn schedules upside down.
All eyes on American to see if Thursday’s bump sticks when the bell rings at 9:30 a.m. ET. Any new operational news could shake things up. After that, the next key test is the company’s quarterly earnings, forecasted for around April 23, per Investing.com. 6
