Every other month, we at TPG go through American Airlines’ schedule to find all of the internationally-configured wide-body aircraft that AA is flying domestically. These flights are great for getting a spacious lie-flat seat rather than a standard recliner seat in business class, and most aircraft have in-flight entertainment screens and in-seat power in economy.However, there’s two notable wide-body AAircraft AAdditions that are coming up in 2019 that are worth highlighting: American Airlines is scheduling internationally-configured Dreamliners on flights to Cancun this winter/spring and Anchorage in the summer.American Airlines is launching Dreamliner service on the Dallas/Fort Worth (DFW) to Cancun (CUN) route on Jan. 6, 2019 — a delay from the originally-reported launch of Dec. 19 — using a Boeing 787-8 on the following flight schedule:AA 2684 — Dallas/Fort Worth (DFW) 1:45pm Departure ⇒ Cancun (CUN) 4:15pm ArrivalAA 2684 — Cancun (CUN) 6:25pm Departure ⇒ Dallas/Fort Worth (DFW) 8:25pm ArrivalBusiness class seats on American Airlines’ Boeing 787-8.Then, from Mar. 3 to Apr. 1, 2019, this route will also get a once-daily flight using a Boeing 787-9, which offers premium economy seats and a better business class product than the 787-8. This flight will operate on the following schedule:AA 1190 — Dallas/Fort Worth (DFW) 9:05am Departure ⇒ Cancun (CUN) 12:45pm ArrivalAA 1601 — Cancun (CUN) 2:05pm Departure ⇒ Dallas/Fort Worth (DFW) 4:10pm ArrivalBusiness class on American Airlines’ Boeing 787-9Then, from Jun. 6 to Sept. 3, 2019, a Boeing 787-8 will operate between DFW and Anchorage:AA 399 — Dallas/Fort Worth (DFW) 3:25pm Departure ⇒ Anchorage (ANC) 7:12pm ArrivalAA 399 — Anchorage (ANC) 8:40pm Departure ⇒ Dallas/Fort Worth (DFW) 6:00am Arrival (+1 day)Let’s go through why this is good news for flyers:Elite Upgrades: As both of these destinations are in North America, they fall under American Airlines’ 500-mile upgrade scheme. That means that Platinum Pro and Executive Platinum elites will get complimentary upgrades to lie-flat business class on these flights — and EPs will even get free upgrades on award flights.AA Gold and Platinum elites will have to “pay” three 500-mile certificates for the 1,028-mile flights between Dallas-Cancun and a hefty seven 500-mile certificates for the 3,043-mile flights between Dallas-Anchorage.Award flights: As these aircraft have significantly more capacity than the aircraft they’re replacing, hopefully this will mean more availability when booking with miles. In addition to nearly double the business class seats, there shouldn’t much competition from business travelers on these mostly-leisure routes.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

See privacy policy.And while American Airlines charges a premium for coast-to-coast award flights in lie-flat business class, there’s no mileage premium charged for booking a lie-flat business class on these routes. So, you’ll get a significant upgrade over the alternatives for the same price.Speaking of the mileage price, flights between Dallas/Fort Worth (DFW) and Anchorage (ANC) are pricing out at:Economy: 15,000 miles plus $5.60 taxes/fees one-wayBusiness: 30,000 miles plus $5.60 taxes/fees one-wayDespite being significantly shorter flights, award flights between DFW and Cancun (CUN) cost the same number of miles in economy plus more taxes:Economy: 15,000 miles plus $32 taxes/fees one-wayBusiness: 25,000 miles plus $32 taxes/fees one-wayPremium Economy Sold as Economy: The last benefit worth highlighting is that all Boeing 787-9 Dreamliners have a premium economy cabin. And, the Boeing 787-8 aircraft are going to be retrofit in early 2019. On the Cancun routes, American Airlines isn’t selling premium economy as a separate class of service, so these extra-legroom, extra-width seats will be coded as “Main Cabin Extra.” These seats will be free for Platinum, Platinum Pro and Executive Platinum elites to reserve at booking.On the Anchorage flights, AA is going to sell the premium economy cabin as a separate class of service. That means that you’ll have to pay a little more to get these seats, but you’ll get all of the benefits of AA premium economy — including better service and catering.
