Japan Airlines 747 SPs were designed for very many short flights, down to
30 minutes even, because the mountainous terrain makes it economical. I
read somewhere that those delivered in the mid-70s were expected to do
52,000 cycles over a 20-year period.

[Moderator's note: That would be SR, not SP.  The 747SP was designed for
very long flights and as such would not have needed a higher cycle life
than a standard 747.  -- Karl]
