Thanks to all for your comments. This is a wonderful site and have enjoyed it plenty the last week or so since I've joined.

Here's my situation. I live in Austin so have 2 great hubs in DFW and HOU for AA and CO respectively. I mainly fly for vacations with my family to South America, Europe and Mexico- only occasionally elsewhere.

I'm Gold with AA and currently have 670K miles- another 700K from Platinum. I just started to earn with CO as well and have 160K miles.

Should I scrap CO and just concentrate on AA? I want to use my miles for rewards, upgrades and status. I get my miles mainly from partner programs and not flying.

Should I maybe consider another carrier as well. I'm 35 and plan to do plenty of traveling in the future. Any and all comments are appreciated.
