Well, I'd love to see Air New Zealand if they get mad enough at Singapore because of the Ansett deal to quit * Alliance, but I don't expect it.
Also, it's a real shame Delta pissed off Aer Lingus by being greedy a few years ago... Dublin would make a really good European mini-hub for Britain. (I hate Heathrow -- what I really like about Bermuda Two is that Delta is consigned to Gatwick -- snicker, snicker -- which I think is better.)
Third on my wish-list: Swissair.
Okay, I know you said "a good concept of who is available..." Sorry.
As to who is available: I'd just as soon NOT see Aeroflot or Air India, but wouldn't really care a lot either way; these aren't markets I'm likely to fly to. Thai might be okay if they decide to decamp *. IMO.

"Service" should be a noun, not a verb.
