As far as I know (and I haven't checked recently, in the past 2 months), BA policy is still to accept interlined luggage on separate Oneworld tickets; in fact I think this might even be a Oneworld policy and BA is required to honour it by their Oneworld membership contract. Maybe someone can shed light on that.[/QUOTE]

I checked the OW website and look what I found...

"Easy and Seamless Connections

The oneworldŽ alliance airlines work together to ensure that your journey goes smoothly from start to finish. In key airports you will find that our transfer desks and customer service desks are clearly marked with the oneworld logo, and our ground staff are on hand to help you with your connection between oneworld alliance airlines.

To make things easier for you, on the majority of flights when you are transferring between oneworld member airlines, you and your baggage will be checked through to your final destination at check-in.

Remember, should a problem ever arise, just contact a representative from any oneworld alliance airline, who will be happy to assist you."

Makes it all sound so lovely and easy doesn't it!!??
