American Airlines, the largest airline and flag carrier of the United States, has been rumored to be considering the Airbus A321LR or Airbus A321XLR, according to One Mile At A Time. The airline has not confirmed whether it will place an order, or which variant the order will be for, however, it is likely that the airline will order the longer-range A321XLR. It is likely that the airline will be using these aircraft to replace its aging Boeing 757 fleet, which is used on long-haul routes between the airline’s hubs at New York and Philadelphia and Europe, as well as on certain routes to South America. The airline’s 757 fleet is approaching 20 years of average age, so the airline will likely replace the fleet soon, and the A321XLR will feature added range over the A321LR, allowing for greater route flexibility. The A321XLR will likely have over 5,000 miles of range, compared to 4,600 for the A321LR and 4,505 for the 757. This will allow for several new route opportunities in Europe and South America, and will open up new routes to Hawaii from the airline’s further east hubs. The A321XLR will likely be announced by Airbus at the upcoming Paris Airshow, and is aimed at replacing Boeing 757 and Airbus A310 aircraft in airline fleets, as well as allowing airlines to operate longer, lower-demand routes, or several flights per day in a long-haul market.
