As I have said in an earlier post, nobody around here in has even heard of OS.
It seems to me that it is marketed as a US-based airline rather than targetting EU customers. To me, it would make more sense to target US customers only when codeshares with AA are permitted trans-Atlantic, thus feeding passengers onto the airline from the AA network. However, today, I would focus upon reducing the duplication of transfers through Heathrow of European-based customers. Further, an AA tieup completely eliminates the need for the venture.
Either way, the whole structure has completely failed to use the BA brand to full effect - the BA brand being one of only two valuable assets in the BA group (the other being the Heathrow slots).
This lends itself to the suggestion that it is nothing more than a vehicle to undercut Ts and Cs - hardly endearing it to current BA crew. Lions led by donkeys again...?
I ask again - why on earth is the integration with L'Avion so slow?
