I am about to fly out on BA. If I credited the trip to BA EC, I would make it to Silver afterwards and reach about 75k miles in my account. I need 100k for a return award in business to Europe. I am also Alaska MVP gold. If I credited to Alaska, I would get more miles from this trip, but my Alaska balance is almost 0 now, so I would not be any closer to my award. On the other hand, it would help me re-qualify next year and accumulate miles I can spend on several airlines. So, do I go for ba silver or for more miles?
