AAAmerican Airlines is one of the main legacy carriers here in the United States but as of late hasn't gained as much positive feedback as Delta or United. American finds itself always playing catch up when it comes to innovation. But they are still a great option for flights throughout the United States and internationally as well as the best legacy carrier on flights to Latin America and South America.
American serves the business traveler as well as the premium traveler, but their product doesn't gain as much notoriety as Delta or United. They are now embarking on long and thin transatlantic travel to secondary European destinations to carve out a niche for themselves with their brand new Airbus A321XLRs.
American by no means is a slouch compared to United and Delta. They are a viable option for business travel, international flying, and flights down to Latin America. But like most legacies, if you're cost conscious you may want to opt for an alternative airline.
American Airlines flies to more domestic and international destinations than any non-legacy U.S. carrier, with a network anchored at hubs in Dallas/Fort Worth, Charlotte, Miami, Philadelphia, and Phoenix. Miami is the standout for international reach: it serves more nonstop routes to Latin America and the Caribbean than any other hub airport in the country.

Per-aircraft performance, 2025
How efficiently American Airlines uses each aircraft type it flies: load factor, seats per flight, and passengers per departure, broken down by airplane model.
Highest-volume city pairs by seat volume
The busiest routes American Airlines flies by total seats, split into domestic and international. Ranked by volume, not necessarily by profitability.
American Airlines owns Dallas Fort Worth and is making a run at United at Chicago O'Hare. American largely settled on flying from secondary business cities in the U.S. like Philadelphia, which allows them to fly under the radar a bit especially since Delta and United have hubs in larger business cities.
The fleet breakdown reflects American's position as a transitional airline: a large Airbus A320 family and Boeing 737 NG base, with growing MAX and A321neo numbers pointing toward where the fleet is heading. The widebody types 787 and 777 post the strongest load factors, consistent with high demand on their transatlantic routes.
Understanding route metrics for American Airlines
Load factor is the percentage of available seats filled with paying passengers. A route running at 85% or above is considered healthy and signals strong demand relative to capacity. When American Airlines routes dip below 75%, it often means the airline is over-scheduling relative to demand, which can lead to fare cuts, frequency reductions, or eventual suspension. Routes where the load factor has declined more than 5 points versus the historical average are flagged in our Stability scoring, since sustained low fill rates are one of the strongest early indicators of a route being pulled.
Route Stability reflects how consistently a route has been operated over time and how healthy it looks today. Lower scores, flagging a route as Stability Watch or At Risk, are driven by a combination of factors: declining year-over-year passenger numbers, load factors below 75% (meaning seats are going empty), frequency cuts in 2024–2025 relative to 2023, and a history of suspension during COVID with a slow recovery. A route that American Airlines skipped during 2020–2021 and never fully restored will carry a resilience penalty that drags the overall stability score down.
Route Dominance looks at American Airlines's share of that route specifically. It is driven purely by American Airlines's seat share on each route: Sole Operator means American Airlines is the only nonstop carrier; Monopoly means it holds over 70% of seats; Dominant means 40–70%; below that falls into Competitive or Minor territory. High dominance on a busy route signals strong pricing power and low substitution risk for travelers.
Airport Commitment scores how deeply invested American Airlines is at each airport it serves, specifically whether it's growing, holding steady, or pulling back. A Dominant or Committed label means the airline has meaningful seat share, stable or growing capacity, and strong route completion rates at that airport. A Marginal or Retreating label means thin seat share, capacity cuts since 2022, or a pattern of cancellations. Hub airports like American Airlines's primary bases will always score highest; airports where it operates only one or two seasonal routes will score lowest.
