Delta Air Lines has encountered challenges in replacing its aging Boeing 757 fleet, which currently averages more than 23 years old. The airline initially planned to use a subfleet of 21 Airbus A321neo aircraft for premium transcontinental services, with commercial service expected to begin in 2024. These aircraft were designed to seat up to 148 passengers, including 12 in first class, 16 in business class with lie-flat beds, and 120 in economy class.

However, the new business class seats have not yet received certification for use on the A321neo from the US Federal Aviation Administration (FAA). Certification is not expected until 2026. As a result, five of these aircraft are currently in storage, with three at Victorville and two at Toulouse.

Delta Air Lines considered leaving the aircraft in storage while awaiting certification but decided it would not be financially viable. Instead, the airline has temporarily reconfigured the interiors by replacing the lie-flat business class seats with an additional 32 first class seats in a 2-2 configuration, bringing the total to 44 first class seats per aircraft. "Although the onboard experience in a domestic first class seat cannot compare with a fully lie-flat business class bed as was originally intended, this plan at least allows Delta Air Lines to put the aircraft to use."

These specially configured A321neos are set to operate on transcontinental routes that connect major business centers such as New York John F. Kennedy International Airport (JFK) and Los Angeles International Airport (LAX). On these routes, Delta currently uses a mix of narrowbody and widebody aircraft, including Boeing 757-200s, Airbus A321neos, Boeing 767-300ERs, Boeing 767-400ERs, and Airbus A330-900s.

The Airbus A321neo is considered suitable for replacing the older Boeing 757-200s due to its similar capacity and range, as well as improved fuel efficiency and lower operating costs. Delta began receiving A321neos in 2022 and now has 84 in its fleet, though only 79 are operational due to storage issues related to certification delays.

The existing A321neos are powered by Pratt & Whitney GTF engines that offer quieter performance and reduced carbon emissions compared to previous-generation models. This supports Delta's commitment to achieving net-zero carbon emissions by 2050.

Despite being a longstanding part of Delta’s fleet since the 1980s, the Boeing 757 is showing signs of age both mechanically and in terms of cabin amenities. Its unique performance characteristics have allowed it to serve both domestic transcontinental flights and certain transatlantic routes that require narrowbody capabilities.

Industry trends indicate a shift toward using narrowbody aircraft like the Airbus A321neo for high-frequency transcontinental operations. This approach offers greater flexibility for premium business and leisure travelers compared to deploying larger widebody jets.

It remains uncertain when Delta’s Airbus A321neos will enter service with their intended business class configuration. In the meantime, retrofitting them for domestic first class enables continued replacement of older Boeing 757s on key routes while maximizing asset utilization.
