In the miles and points world, putting your frequent flyer number on your flight reservations is probably second-nature for the most part. In fact, my frequent flyer number is generally listed on all of my airline accounts, so a lot of the time it shows up automatically when I am flying. However, because I often fly with a family of 8 AND we have several different people with different accounts. So depending on whose account we’re using, everyone’s frequent flyer numbers may or may not be on the account. And I will admit that sometimes, especially when it’s an award booking where I know we won’t EARN miles, I don’t always bother putting everyone’s number in.

Our Recent Delta Flight From Paris

But that nearly came back to bite me on a recent flight from Paris. Thankfully it all worked out in the end, but I was definitely annoyed with myself at first. We had booked our flights from Paris to Cincinnati on Delta but using Virgin Atlantic miles. Because my wife already had some Virgin Atlantic miles in her account from a previous trip, we transferred Chase Ultimate Rewards points to her Virgin account. For some reason my Delta frequent flyer number along with the numbers for my 2 kids were added to the reservation, but hers was not (maybe it had to stay as her Virgin Atlantic number?).

This wouldn’t have even mattered, except that our flight was cancelled! Thankfully Delta rebooked us all (on an Air France business class flight) but the 3 of us who had our account numbers all got automated emails from the infamous Rose O. Dougherty from Delta granting us 20,000 Sky Miles “for the inconvenience)

My wife (whose Delta frequent flyer number was NOT on the reservation), did NOT get an email with 20,000 bonus miles.

How It Ended

I would have been pretty bummed if that had kept us from getting 20,000 miles (though that was in addition to the Delta EU261 compensation that we also got). But thankfully, a quick email to Delta Customer Care got her the 20,000 miles as well. So I am glad that worked out for us, but it would have been easier if we had just put everyone’s frequent flyer number on the reservation. Plus, I feel like including your frequent flyer number on the reservation helps to make sure that you are more easily contacted if there are any kind of irregular operations or flight delays.

The Bottom Line – Always Put Your Frequent Flyer Number On Your Reservation

While this may be a minor thing, and it all worked out for us in the end, I thought it was worth a quick PSA to encourage you to always put your frequent flyer number on your reservation. It may be able to help you in case of irregular operations and it lets you be more easily contacted in case the airline needs to get a hold of you.
