On two recent Delta MD-88 flights I noticed that the chimes consistently
sounded when passing through 16,000 ft rather than the 10,000 ft that I
had expected.  This was according to my GPS (accuracy within 1500 ft).

I do remember on the Key Airlines 727-100's (which I flew very frequently
several years ago) they were always set for 10,000 ft.
