Q: How do I track my miles?
A: Depending on the communication cycle of each program, and whether you are an active member, you will receive an account statement by mail or e-mail every one to three months.
The most reliable and up-to-date account information is available through the websites of most airlines. With your membership number and PIN, you can access your account any time you wish.
If you participate in several programs and maintain multiple accounts, you can use a content aggregation service like Mileage Miner, which consolidates data from all your accounts into a single online statement.
However you track your miles, you should reconcile your earnings against what your statement says you earned. Keep copies of boarding passes, tickets, and receipts for all mileage-earning transactions until they have been posted to your account.
