Delta Air Lines: widebody fleet revamp on the horizon


Delta Air Lines has touted the benefits of its upgauging strategy for years, and its narrowbody upgauge continues in 2019 as it builds up a fleet of Airbus A220 narrowbodies. The airline has calculated that it will be refleeting up to 35% of its mainline fleet during the next five years.

At YE2018, Delta was preparing for the first revenue flights of its A220s on routes from New York LaGuardia to Dallas and Boston. The airline touts that the aircraft offers a superior experience to its existing equipment while driving down costs.

As its narrowbody revamp and upgauge from regional jets continues, Delta is turning part of its attention to a widebody fleet revamp for replacement of ageing Boeing 767 and 757 jets. The airline has cautioned that it is a process that will take a while; but the company is no doubt carefully studying its options as the 767s are scheduled for retirement over the next decade.


  • Delta touts the cost and product improvements from its continuing aircraft upgauge programme.
  • Delta believes the Airbus A220 offers better costs and a better experience for the customer.
  • The airline is working to determine the future composition of its widebody fleet, and it remains to be seen how Boeing's potential middle of the market aircraft factors into those evaluations.

Delta is near the middle of a years-long single aisle upgauge programme

Using a baseball analogy, Delta executives have concluded that the airline is in the third or fourth inning in a years-long fleet upgauge designed to offer passengers a better product, to enlarge margins and to cut costs. Delta, the world's most profitable airline, has one of the oldest fleets in the world and is gradually upgrading.

The airline started by upgauging its 50-seat regional jets that were less fuel efficient, and limited in their revenue generating abilities due the airline's inability to configure the jets with a premium cabin.

Delta has calculated that on a 900 mile stage length, with fuel costs of USD2.25 per gallon, the cost per seat with upgauging is significant, and believes that next generation aircraft technology provides more opportunity to drive down costs.

The 109-seat A220s are replacing Bombardier CRJ-900s and the Embraer 175s, and the A321neos scheduled for delivery beginning in 2020 are replacing MD-88s, which are slated for retirement by YE2020.

Delta calculates that by 2023 45% of its domestic seats will be part of large mainline aircraft, compared with 30% in 2018.

As of mid Dec-2018, Delta has already accepted delivery of two A220 narrowbody jets and expects to add 25 more in 2019. The A220 is scheduled to start revenue service at the end of Jan-2018, from the airline's New York LaGuardia hub to Boston and Dallas.

Recently, Delta executives offered insight into the launch of A220 services, company president Glen Hauenstein noting that New York to Dallas "seems like a long way to go on a 76-seat RJ".

Mr Hauenstein explained that with its wider seats, larger windows, bigger overhead space and quieter interiors, the A220 offers customers a much better experience. "And the great part about that is our cost of production for the same flight is actually going to go down", he stated.

Company CEO Ed Bastian also endorsed the A220, noting "we're going to take 25 of them next year [2019] and they're right on schedule". He also added: "One of the things the Airbus brings to the platform is scale with the supply chain to continue to help Bombardier not only keep the product flowing in terms of accelerating the order book, but also bring the price points down, the cost points down for the company."

Delta begins to consider 767 and 757 replacements

Delta's domestic upgauging has been a point of pride for the airline for a number of years, but the airline is just starting to evaluate its wide body fleet replacement.

CAPA's fleet database shows that Delta operates a total of 150 widebody aircraft, representing 17% of its total aircraft in service.

The airline has 49 widebodies on order, representing 15% of its total order book.

The airline plans to retire its 79 elderly 767 widebodies during the next decade, and is also planning 757 retirements.

In 2016 Delta finally cancelled a 787 order it had inherited from Northwest during their merger in 2008, after ordering A350-900s and A330-900neos. In late 2018 the airline added 10 of the A330neos to its order book, for a total of 35, and pushed back deliveries of 10 A350s.

The A330-900s are replacing some of the 767-300ERs in Delta's fleet (as of late Dec-2018, Delta had 56 -300ERs in its fleet, with a median 767 fleet age of 22.7 years). The A330s have 50% more premium seats than the older widebodies and the airline has calculated that the aircraft have a 22% better fuel burn per seat.

The A321neos are replacing the MD-88s and some of Delta's 757s, and the fuel burn improvement per seat for the A321neos versus the MD-80s is 40%, with 50% more premium seats.

Delta is keeping its options open on how it will ultimately approach the widebody replacement.

The airline has expressed an interest in being the launch customer for Boeing's middle of the market aircraft, and Boeing has recently stated that it has discussed the aircraft type with more than 60 customers worldwide.

The manufacturer's consistent message is that it plans to make a firm decision regarding the middle of the market jet in early 2019, so Delta is also waiting for Boeing's decision as it works to determine the future composition of its widebody fleet.

Presently, Delta's widebody order book is more weighted toward Airbus; however, the airline will no doubt conduct a competitive campaign for replacement of its smaller widebodies.

But Delta could also need replacement aircraft before a middle of the market aircraft enters service, which could open opportunities for Airbus if the airframer can provide Delta with favourable terms for additional orders. Airbus has shown a certain level of flexibility towards Delta, given the recent pushback of A350 deliveries and the expansion of Delta's A330 order book, and would no doubt also welcome an opportunity for expansion of the A321neo order book at Delta.

Delta works to make its fleet composition competitive for decades to come

Airline fleet management is a living science; Delta is working to create a fleet composition to maximise efficiency and costs while continuing to widen the competitive gaps in the passenger experience that it has with respect to its large US global network rivals.

In many ways, Delta is behind its rivals with its fleet revamp, but the airline remains long on ambition in working to create an operating fleet to keep it competitive for the long term.
