I am puzzled by this. If one understands CX38 or whatever has MAN declared as the Alternate in its flight plan, and that is a stored flight plan used everyday CX38 flies, and if they have a contract in place with MAN to handle that flight as and when diverted, then how can it be turned away on the basis posted here ? Has MAN informed CX and every other airline that MAN cannot be a designated Alternate ? Has MAN informed CX and every other airline that has a contract in place to handle diversions that it will not honour that contract ?
