What If I … Forgot to Use My Frequent Flyer Number? (And Other Frequent-Flyer Information)

A quick phone call is often all it takes to resolve many frequent-flyer issues.

The world of frequent-flyer programs is large and confusing. If your account’s not active, your miles expire. Terms and conditions are always changing. And what about airline alliances?

You might want to say, “I don’t care about any of this stuff. I just want to get a free trip every 150,000 miles.” Unfortunately, it’s not that simple.

The simple part is actually becoming a frequent flyer. It’s as easy as finding the signup button on your favorite airline’s website. You’ll fill out a form with basic information like name, address, and email, and have to some answer fun questions like seat and meal preferences. Then you’ll receive a congratulatory email with your frequent-flyer number.

Save this email until you receive your frequent-flyer card in the mail, because that number is how you start earning miles (the whole point of filling out that fun form).

There are many ways to earn miles, including credit cards, airline dining programs, hotels, and surveys. If you’re interested in delving into the intricacies of point-earning, some great resources include our friends Ariana Arghandewal (PointChaser) and Kendra Collins (Points and Pixie Dust), as well as The Points Guy.

The most obvious way of earning miles is by flying. When you book a flight online, whether on an airline website or on the site of an online travel agency (like Expedia), enter your frequent-flyer number when prompted. If you book over the phone, you’ll be asked for your number, and if you book through a travel agent, be sure to give them your number if they don’t automatically ask for it (which they almost certainly will). They’ll also help you sign up for any frequent-flyer programs you don’t belong to.

Finally, it’s departure day. Be sure to present your card to the agent when you check in for your flight, or if you do auto check-in, make sure it’s entered on your ticket. If it’s not, most auto-check-in procedures let you add it at some point in the process.

If that doesn’t happen, or you forget to take any of the other steps to get your miles, don’t worry; your miles aren’t lost. You’ll just have to take a couple extra steps to claim them.

The general process for requesting missed frequent-flyer miles is to  log into your frequent-flyer account and fill out a form.

Each airline and miles program has a slightly different process for claiming missed miles, but the general procedure is to log into your frequent-flyer account and fill out a form to request missing miles. (This is the same form you’d fill out if you did give your frequent-flyer number and your miles weren’t credited to your account.) The form asks for basic flight-related information, like flight date and ticket number, that can be found on your boarding pass or flight-confirmation emails.

A good rule of thumb is to hold onto your boarding pass until you know your account has been credited with the miles you earned. Your boarding pass is proof you were on the flight, and it has the information you’ll need to claim your miles. You also might have to send a copy of your boarding pass to get credit for the miles you missed.

(Editor’s Note: Here’s a handy tip: Take a picture of your boarding pass as soon as you get it. It can not only help you get any frequent-flyer miles you missed, but if you have AirCare from Berkshire Hathaway Travel Protection you can also send the picture to jump-start the claims process.)

How long you have to claim missed miles depends on the airline. The general timeframe is between nine and 12 months after a flight, but don’t take that as a reason to put your claim on your To-Do-Later list. It’s smart to claim missed miles right away, because you never know if you’re going to run into problems trying to claim them.

One reason for the long timeframe to claim miles is because many frequent-flyer programs let you claim miles from any flight you’ve had with the airline during that time, including flights you flew before becoming a frequent flyer. Those rules vary between programs, so if you’re a recent joiner, there might be an opportunity to garner additional miles from an earlier flight.

Now, remember those airline alliances we talked about earlier? You have more opportunities to score miles if your airline is in an alliance.

The three major airline alliances are Star Alliance, Oneworld, and Sky Team. Miles earned in any one of the member airlines’ programs can be credited to the alliance, and can be redeemed on any other airline in the alliance. So if you’re a frequent flyer with American, you can fly on British Airways and credit those miles to your AAdvantage account, because both airlines are part of Oneworld. And then if you’ve accumulated enough AAdvantage miles, you can redeem them for a flight with fellow Oneworld member Cathay Pacific.

Finally, note that not all miles are created equal, especially when it comes to expiration. Some types of miles expire faster than others, and this varies from program to program. Make sure your miles don’t expire! You went through all that work to earn them; it’d be a shame if they just disappeared.
