Ok, need adult advice here. Long story short: apparently some people in my company can not be trusted with company cards, so we had to all hand them in. They said if you have travel expenses for a trip, you can get a temp card from them for that purpose. I only use mine for travel anyway, so I asked the boss about getting my own card to earn points and just get reimbursed for expenses. (There may be a tax issue here I'm missing that someone can fill me in on.)
So now I'm looking at getting a card to earn miles for flights. My inclination is to go with an AA card because I already have an account collecting miles with them and do all my flying with them, so it makes sense to be able to double up. Am I being myopic here by not looking at other options? It doesn't seem like most travel points cards play nicely with airline specific miles.
