Fuel savings are key to a functioning aviation industry in this next chapter. From rising costs to environmental impact, airlines have had plenty of reasons to save every bit of jet fuel they can. Delta Air Lines this week revealed details of how its fleet renewal program has helped to save tens of millions of gallons of fuel.

New additions

Delta had a busy 2021 regarding new aircraft. The Atlanta-based carrier recognizes that renewal is the best way it can boost its fuel efficiency. So, it’s not a coincidence that the carrier has been keen to deploy new units in recent years. After all, sustainability is one of the company’s core pillars in its fleet strategy.

Last year, the airline received a total of 52 next-gen aircraft that are an average 25% more fuel-efficient per seat mile than retired models. Subsequently, Delta improved its year-on-year fleet-wide fuel efficiency by 0.8% in 2021. While this percentage may not seem like much, in practice, it forms a saving of 22.5 million gallons of fuel.

When it comes to new orders Delta added 30 Airbus A321neos to its order book last August. The model's Pratt & Whitney PW1100G turbofans provide a 12% better fuel efficiency on a per-seat basis than its older ceo siblings. Also, these engines will be maintained by Delta TechOps technicians to keep them in top shape in the long term.

Overall, a mix o fleet renewal and operational initiatives are driving this improvement. On the long road to zero emissions, airlines have to ensure that they are heading in the right direction. So, Delta is continuing to spend big on sustainability schemes, including the scale-up of sustainable aviation fuel. On the narrowbody front, the A220 is bolstering Delta’s holdings with modern options, and the airline took its milestone 50th delivery of the type last summer.

When it comes to long-haul operations, the A350-900s and A330-900s are moving vital in the efficiency-lowering mission. These widebodies are combining well on international journeys.

Strong commitment

Overall, Delta is determined to achieve net-zero by 2050. It has already shown its commitment with billions of dollars invested across its fleet and wider operational network.

Ed Bastian stated the following about his company’s investments in Delta’s 2021 ESG Report:

“In 2021, Delta made capital expenditures of approximately $3.2 billion, the majority of which went toward new aircraft that are, on average, 25% more fuel efficient per seat mile than retired aircraft, as well as terminal construction that includes enhancements to energy efficiency. In addition, 25% of our ground equipment is expected to be electric by the end of this year, increasing to 50% by 2025. We’re also continuing to look for opportunities to form innovative partnerships and coalitions and to sign new sustainable aviation fuel (SAF) agreements.”
