Hello, I have received conflicting info from the AA RTW phone reservation line about seat assignments on FINNAIR. This made me want to ask if anyone has compiled a list of the Oneworld airlines and how to get seat assignments on each one. A complete list would be helpful.

My current issue is with Finnair whose website will charge for seat assignments. One agent said after the business class ticket was paid for AA could make the seat assignments. When I called to do that, the agent said the Finnair's policy would only allow Oneworld Emeralds to make seat assignments.

Anyone have info about seat assignments? Cathay Pacific, etc.? Thanks.
