But you are correct in that the 747-SP had the highest operational ceiling out of all the 747 series. The SP was rated to 45,100 ft, while all others are "only" rated to 45,000 ft. Perhaps just a rounding error from 13,700m?

It may just be that they scrambled for some altitude that flight due to the mets - it certainly didn't loiter as we departed PPT.
Could be the rounding error due to metric conversion; we have some boffins who are even less accurate than that, and sent a probe crashing down because of it. Maybe they were working for Boeing at one time?

But with the same power and less weight than the -100 and -200's of the day, they could get to the prefered altitude quicker. They didn't need to burn off as much fuel before being able to get above FL350. QF operated their 747-SP's with RB211-524D4 (53,100lb) engines, the same as the -200 and -300 models they operated.
