American Airlines will first deploy its brand-new Airbus A321XLR from New York JFK to Los Angeles. While entirely unsurprising, it is good to see it scheduled and bookable finally. The first departure is set for December 18. This revelation came as Air Canada added the XLR on its fifth transatlantic route.
American is the first US operator of the XLR. It now has three frames. On October 22, one aircraft arrived in Dallas/Fort Worth after an 11-plus-hour flight from Hamburg Finkenwerder (the aircraft didn’t have passengers or freight), while two aircraft remain stored in the Czech Republic. It has 50 of the much-delayed aircraft on order. They’ll have just 155 seats: 20 business class suites (1-1), 12 premium economy seats (2-2; similar to domestic first), and 123 main cabin seats.
Entry Into Service Is Set For December 18
Subject to further changes, the 
oneworld member has confirmed that the XLR’s entry into service will take place on December 18, which is a week before Christmas, with the consequent higher traffic. While a daily round-trip XLR service will initially operate, as discussed below, it’ll be used up to twice daily thereafter.
It will initially be on AA3. This will depart from 
New York JFK at 11:00 and arrive in 
Los Angeles at 14:18 local time. Returning, AA4 will leave California at 15:20 and arrive back in the Big Apple at 23:46 local time. This is the US’s most-trafficked airport pair, and it generates the highest revenue.
The XLR will, of course, replace the so-called A321T, with the ‘T’ standing for ‘transcontinental’. (American likes adding letters to aircraft. It does it to the Boeing 787-9, too.) Its A321Ts have just 102 seats; they’re extremely high-premium.
Its A321Ts have ten seats in first class, 20 in business, and 72 in economy. The switch means AA3/AA4 loses first class but gains a better business product, along with premium economy and many more seats in economy. American is reconfiguring its A321Ts anyway. They’ll have 190 seats instead of 102.
A Look At The JFK to Los Angeles Market
American is one of four operators on this most significant of US domestic airport pairs. It joins Delta, Frontier, and JetBlue. Sticking with Los Angeles International, Newark has nonstop service by Alaska Airlines, JetBlue, Spirit, and United. Due to the highly limited perimeter rule, which only permits Saturday flights on such long routes, LaGuardia is not served—but it was until 2023.
Let’s focus exclusively on JFK-Los Angeles. Between December 18 and 24, when the XLR is due to operate, Cirium Diio shows that the quartet of carriers will have 194 weekly departures. Daily flights will vary from 22 to 31 in each direction. Each carrier’s offering is broken down below. With 59 weekly services, American has 31% of the market. Given that it no longer uses widebodies, its share will obviously be lower than this for passengers, seats for sale, and available seat miles.

Despite the entry of Frontier in May 2025, the 194 weekly departures are only up from 192 services in the same week in 2024. And they are down from 243 in the same seven days in 2019, just before the world temporarily changed due to the pandemic. Alaska Airlines operated then, but it pulled out in 2021 to consolidate at Newark.
A Day In The Life: American Flights On December 18
On Thursday, December 18, American will have nine daily departures from JFK to Los Angeles, which is the world’s ninth-busiest airport.

It will have the joint-earliest departure.
It will have ten flights back to JFK. They’ll go at 00:11 (A321T), 06:10 (A321T), 07:00 (A321T), 08:10 (A321T), 10:15 (A321T), 11:35 (A321T), 12:35 (A321T), 15:20 (A321XLR), 21:05 (A321T), and 22:50 (A321T). When all carriers are included, its 00:11 departure will be the latest (or earliest) on this airport pair.
