Apologies, FT has been inaccessible for me the past several days.

If you are wanting some kind of official OW involvement in the do (like the *A one) then it will likely require someone with good contacts with OW &/or 1+ main airlines within the alliance in order to get anything arranged.

Everything else is mere wish list and speculation.

If anyone does have such contacts and can help out then please post here, or contact the OP or me by PM/email.
