I have two passports with different middle names. Which one should I register as my account name?

We suggest that you register with the name shown on the passport you use most frequently for your flight tickets. If you travel with your second passport in the future and wish to claim your miles, you must provide copies of both of your passports to us through email, stating your issues, so that we can help record your name as it appears on your second passport.
