Update: It now appears that AA flyers can check their AAdvantage account summary to see how many qualifying miles they’ve earned for each past flight. View From the Wing is reporting that presumably EQDs will be added to this list next year. This is a very welcome addition from American, now allowing members to check their EQM earning from all flights — a feature that wasn’t previously available.You can now see your earning on past flights on the AAdvantage account summary page.If you’re an American Airlines frequent flyer — or you simply follow the major US carriers — you know that the AAdvantage program is switching to a revenue-based redeemable mileage-earning system. While it’s generally not the best news for AA flyers, it will benefit those who spend a lot with the carrier. But for those who are after the cheapest ticket available, the changes don’t exactly work in your favor — as of August 1, you’ll earn miles based on how much you spend, not how much you fly.On the positive side, the carrier is now making it easy for you to track exactly how many EQMs and redeemable miles you’ll earn before you even book your ticket. This change to AA’s website and the booking process comes in advance of the pending AAdvantage program change, which gives flyers some time to understand how the new process will work.A sample of what you’ll see when booking — EQMs, EQSs, EQDs and total award miles.Note that you won’t get to see these earning numbers until just before you book — you must go through all the prior booking screens. As a reminder, you’ll earn more miles if you have higher status:Ultimately, this is a change for American that came earlier than expected — although the actual AAdvantage program changes aren’t welcomed by all. In any case, this tool will come in handy when you’re plotting your progress toward elite status.H/T: One Mile at a TimeSign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
