My understanding of this hasn't significantly changed since you asked the same question in mid-December.

The last letter I received (dated January 6th) said that discussions were taking place with JAL about them joining OneWorld (see BA thread) and other operators were in discussion (Air Lingus is amongst the possible).

The initial integration of FF schemes was due to take place in March. There were several reasons for this including some existing realtionships having to be severed (ie. Malaysian and Singapore in the case of BA) and it was hoped some other airlines would be announced by then.

There is still the possibility that the March date may slip if other carriers are "on the verge" of joining OneWorld.

The last letter I have also hints at "service inequalities" being an issue, I know that OneWorld wants it's schemes to be more uniform that StarAlliances (ie. they do not want inequalities in Lounge Access etc).

I hope that helps. I think the message is hang in there!
