My husband and I have just signed up for a bunch of credit cards to get the bonus miles. Now I am unsure how to focus my future spending and flying activities. Can anyone help me figure out which carrier would be best to focus on? Issues I am thinking about include: Whether it would be best to pursue status on one airline and then get another airline to match it? Who has a better program for my purposes? Which program is easiest to earn miles with? Which program offers easiest reward redemptions? Some facts about me--I am in Washington DC and like to focus on international travel, especially to Europe. I am very interested in upgrades, mileage awards and perks like free companion tickets. I currently have 150k on AA, 75k on CO, and 50k Amex MR. As you can see I am just beginning to get serious. I have been reading and reading, but still think it would be helpful to discuss this with seasoned travelers here. And yes, I do coins! Thanks for any help!
