how may alliances are there??
 

this may be in the wrong place but how many aliiances are there??

i know of 3;
*alliance
skyteam
one world

are there any others??

Those are the only three with names and the only three worldwide ones. There may be (now or in the near future) some regional alliances, where, say, groups of LCCs in adjacent countries form a multi-partnership, but that's not an alliance in the sense of the above 3 (for one thing, it's mostly about just cross-earning and cross-redemption, rather than benefits).

And, of course, there are partnerships between individual pairs of airlines all over, including some that include elite qualification possibilities and some that may include some sorts of benefits.

There are quite a few code-sharing "alliances", common-ownership "alliances" (Frontier/Midwest), and other types of points-earning/burning, status alliances.

But those are the three major, global alliances.

don't think this is the appropriate place (MilesBuzz) to ask this...

but ain't you able to use wiki? =) http://en.wikipedia.org/wiki/Airline_alliance
if it's out of date, update it!
