Early analysis shows that operators of Next-Generation 737s are starting to see a 15-percent reduction in maintenance costs, a goal that was established when the program was launched in 1993. Reducing fleet costs is a key issue that directly affects every airline's bottom line. Fleet maintenance costs can range from 10 to 20 percent of total airplane-related operating costs. Since many of the larger airlines have maintenance budgets in excess of $1 billion, the savings can be substantial.
