I'm a newbie. I have both of these cards and use them primarily in my business. I do 90% of my travel with AA because I like to have the status. I also enjoy using the miles that build up for family vacations. I use the platinum for the airport perks, etc. Here's my questions: should I buy my plane tickets with the Citibusiness AA card or book my travel with the platinum through AE travel? I figure I need to pick one and stick with it. Not sure which is best. Pros/Cons?
