I hear a certain Lufthansa employee was spotted with a small entourage at Aer Lingus' HQ last Monday, could we finally see Aer Lingus re-joining an alliance in 2013? It's hard to see which alliance they could be headed for, Oneworld although possible seems now a longshot with the BA codeshare close to being ripped up by the looks of it. Star Alliance seems to be #1 in the running, SkyTeam shouldn't be ruled out however. Mueller's recent comments that any alliance would be outweighed by costs associated with it seems to have been addressed, we should be hearing this announcement soon I gather.
