Mexicana to leave Star?

Quite a shock:
November 07, 2003 – The members of Star AllianceTM have today agreed to discuss a termination of the membership of Mexicana Airlines in the global alliance at the next regular Alliance Management Board meeting on November 13 in Frankfurt, Germany.

The decision follows the official announcement of the termination of the bilateral relationship between United Airlines and Mexicana Airlines earlier today.

In a joint statement, the members of the alliance “regret this development but do not see any other solution for the future of our business partnership. The combined strength of the Star Alliance membership will ensure that the international air travel market, and in particular Mexico, will remain well served by our team of high quality airlines.”

So it seems as if Mexicana wants to leave. I wonder what is going to happen, are Mexicana and Aeromexico going to be merged or is Mexicana looking at other alliance options? Either way it leaves a hole in central American operations for United and Star as a whole.
