I've got AA, CP in the bag and BA coming but need a 4th. I'll be staying at the Sheraton across from AMS from 12/25-26. I would'nt mind taking a side trip to Spain or Finland but have only found high-priced fares at this point.
Thanks for any help.

P.S. - This is my first post, this site is great and the messages I've read have helped me to add many bonuses. From this trip alone (SFO-ORD-LHR-AMS-LHR-LAX-SFO) I should see 53K miles including 25K from OneWorld - Thanks much!
