How Much Does An Airline Save By Keeping A 20-Year-Old Jet Instead Of Buying A New One?

Keeping a 20-year-old jet can look like an airline’s easiest savings move, especially if it already owns the aircraft. That avoids new acquisition costs—tens of millions of dollars in many cases—plus financing arrangements and the higher lease rates tied to scarce next-generation planes. But the comparison isn’t so simple. Older aircraft typically burn more fuel and become more expensive to maintain as they rack up flight hours and cycles. The key question is whether the lower capital outlay outweighs higher recurring operating costs versus buying or leasing a newer model. The article illustrates this by comparing a Boeing 737-800 with a 737 MAX 8, noting potential fuel burn reductions of about 20%.
