I know my company flew a 747-200 til it had ~140,000 hours on the airframe.
We have the very first -400 that was converted to a freighter, N740CK, and it is only around 70,000 flight hours, so about 50% used up. It's an older -400 as we actually had three classics that were newer airframes. Boeing was still pushing out -200 cargo airframes when it was built.
We also have the newest -400, the very last one built. The flight mechanic refers to it as a -600 as it has a lot of updates in the avionics bay from the -8, also has -8 landing gear.

At some point the necessary repairs will get too expensive.
Although it looks like the USAF will operate the B-52 as a front-line combat aircraft for 100 years total. Of course they built them to last back then.
