FAA Registration: Delta is building wings with doors on its Airbus A321 Neo planes

Most of the time, it's worth taking a closer look. This is also the case with the application submitted by Airbus to the US Federal Aviation Administration and to the European Aviation Safety Agency. There it applied for approval for doored business class suites for the Airbus A321neo.

The document states that it is a product from a US provider. No name mentioned. But as keen observers have discovered, the file name of the document reveals which airline it belongs to. Because that is where the abbreviation DAL stands. This usually means Delta Air Lines.

Routes have not been confirmed yet

So, according to speculation on frequent flyer forums, it is possible that Delta One Suite or a similar product is also installed on the airline's long-haul planes. It has not been confirmed on which flights Delta will use the Airbus A321neo with the product.

Rival airlines American Airlines and United are also planning suites on mid-range jets, but only on their extra-long-range Airbus A321 XLR jets once they are delivered. Jetblue flies with wings on its Airbus A321 Neo – but without doors. In addition, the number of seats and class arrangement in the document does not match that of Boston Airlines.
