You've identified a pattern that many airlines follow, but AFAIK there's no rule.
Usually codeshares have a designated, rather high range. For example, UA-marketed flights on SkyWest (flown as United Express) are in the 6000s. I think UA codeshares on US are in the 2000s.
UA often pairs consecutive numbers, at least for international flights. UA888 is PEK-SFO; UA889 is SFO-PEK. UA888 is surely deliberately chosen--8 is a very auspicious number in Chinese culture. The number 4 is very inauspicious (it sounds like the word for "death"), so if the PEK-SFO flight were UA444 it would be very lightly traveled (at least by Chinese).
I remember once flying flight 1776 from LAX to BOS, I think on DL. I was pretty sure that was deliberate too.
Anybody else have examples of obviously significant flight numbers? Is there a 321 or 3210 to MCO (the major airport nearest to Cape Canaveral)?
