How many times have I heard that announcement: " If you need any assistance at all after leaving the plane, please contact our ground staff or any of our One World partners, who will be pleased to help you "

What does that actually mean? Can you imagine.....

I need my BA e-ticket re-routed and re-issued, can you help me Mrs Finnair?

My luggage was damaged on BA, what are you going to do about it, Senor Iberia?

Can you check me in for my return BA flight, Senora LAN?

DYKWIA, Mr American?

What about you, Miss Lingus?

Does anyone know, how a OW partner could help with any BA specific issue, apart from selling a ticket on their own airline? And what the point of this statement is?
