Aircraft age isn't in years, but in number of pressurisations (takeoff/landing cycles). A low cost airline optimising their schedule to squeeze every second of their airframe with constant short distance hopping around would result in much more of those compared to a legacy airline's widebody that is flown daily on a very long flight. So it depends on aircraft type/size and usage patterns, but Ryanair's 737 will be able to handle less years than DHL's 767Fs.
So for the 747 in the story, 22 years is on the long end, but not unheard of.
- RheingoldRiver 4y agoDo the climates a plane flies in and out of make a difference too, or is this such a minor factor compared to the act of pressurization that it doesn't matter? I remember flying out of Chicago once when I was a kid and having to wait for us to be coated in some special fluid because it was so cold that day that the takeoff was going to be especially stressful on the aircraft otherwise.
