What is the lifespan of a commercial jumbo jet?

The typical lifespan of a commercial jumbo jet, such as the Boeing 747 or Airbus A380, ranges from 20 to 30 years, depending on factors like usage, maintenance, and technological advancements. Airlines often retire these aircraft when they become less economically viable due to rising operational costs or fuel efficiency standards. Regular maintenance and upgrades can extend their operational life, but ultimately, advancements in newer aircraft designs usually lead to their retirement.
