AY will not check luggage through...think they are yet to read this part of the oneworld website: 'At oneworldŽ, our member airlines work together across the network to ensure the seamless and efficient transfer of your luggage.' Please give them feedback.
Oh well, I'm sure i will enjoy the immigration/baggage/checkin/immigration experience, if nothing else it will keep me out of the bar for an hour or two. I might give AY a bit of feedforward contact to check on their own interpretation of seamless, guess that bit works only on one ticket.
