It’s hard to imagine that a simple error could cost thousands of points or miles, but that’s exactly what happened to me while booking a flight to Cancun<\/span> for my friends and me.<\/p>\n

I’ve always been diligent about managing my rewards since I’ve heard horror stories of people losing large chunks of their balances through one mistake or another<\/span>. But nobody’s perfect: I put too much trust in my account to auto-update after a points transfer, and it ended up costing me 15,000 miles.<\/p>\n

Here’s what happened and how you can avoid making the same mistake<\/span>.<\/p>\n

The transfer: Moving Membership Rewards to Delta SkyMiles<\/h2>\n

Two of my friends and I decided to go to Cancun this summer, and I volunteered to book us with points and miles<\/span>.<\/p>\n

At the time, I had close to 200,000 Amex Membership Rewards<\/span> points, so Delta Air Lines was at the top of my list of airlines to consider, since it’s one of Amex’s transfer partners<\/span>. I knew I could easily book a few tickets to Cancun and still have a ton of points to spare.<\/p>\n

One of my friends wasn’t flexible on our travel dates due to her work schedule, so I kept a close eye on Seats.aero<\/span> to find the best option for us. Delta turned out to be the cheapest option for our flight to Cancun, perfect luck for me.<\/p>\n

In total, I’d need to transfer 69,000 Membership Rewards points to Delta SkyMiles to book this flight from Seattle-Tacoma International Airport (SEA) to Cancun International Airport (CUN)<\/span>. So, that’s exactly what I did.<\/p>\n

Historically, my transfers have been credited to my account immediately. This time, though, the miles didn’t post right away<\/span>. I made the transfer on a holiday weekend, and I’d heard transfers can sometimes take a couple of days to post, so I waited.<\/p>\n

Big mistake.<\/p>\n

The mistake: Waiting too long to contact Delta support<\/h2>\n

I waited a few days after my transfer to contact Delta support.<\/p>\n

My loyalty account balances have always auto-updated after past transfers, so, at the time, I thought Delta’s system was just taking a long time to process my transfer.<\/p>\n

In reality, the transfer had posted right after I made it. When I contacted support, a representative confirmed that my updated balance wasn’t showing on my account due to a technical issue on Delta’s side. The fix to see them was simple: log out and back in.<\/p>\n

As soon as I logged out and in, the problem was fixed. My 69,000 SkyMiles were available.<\/p>\n

I immediately navigated to Delta’s booking page to snag three award tickets, only to find that the flight I’d chosen had gone up in price<\/span> in the few days since I last checked.<\/p>\n

It wasn’t anything jaw-dropping, but it wasn’t a painless increase, either. In total, I had to transfer an additional 15,000 Membership Rewards points to Delta to cover the additional cost.<\/p>\n

I’m fortunate to have a significant Membership Rewards balance, thanks in large part to the welcome offers I earned from my American Express\u00ae Gold Card<\/span> and American Express Platinum Card\u00ae<\/span>.<\/p>\n

If those 69,000 points were all I had<\/span>, I would’ve been in a very tough spot. Transfers are always one-way, so I wouldn’t have had the option to use those points for another airline.<\/p>\n

The lesson: Always be proactive about contacting support if your transfer isn’t posting<\/h2>\n

The mistake itself was easy to avoid. I should’ve contacted support after 24 hours, since my previous transfers always posted instantly. Any unexpected delay in your rewards posting is worth contacting support about, just in case there’s a glitch.<\/p>\n

Even if nothing’s wrong, take it from me: It’s better to be safe than sorry.<\/p>\n

This is especially true if you’re using most or all of your rewards balance for a transfer, or if your travel dates are inflexible<\/span>. Of course, you could always buy additional points or miles<\/span> if you need more and don’t have any left to transfer. But that can get costly if you need to buy a substantial number of points and miles.<\/p>\n

In the end, the best strategy is to contact support if something feels off. Don’t trust that your account balance will display properly.<\/p>\n

Bottom line<\/h2>\n

In the end, I was able to book the flight for my friends and me. 15,000 SkyMiles didn’t annihilate my rewards balance, but it took enough of a chunk for me to learn an important lesson.<\/p>\n

I spent so much time focusing on big picture things like using the right card<\/span> for certain purchases and monitoring award trackers<\/span> that I missed something so simple. If you plan to make a transfer to Delta SkyMiles soon, remember to log out of your account and back in after the transfer completes.<\/p>\n

Above all else, don’t hesitate to contact your loyalty program’s support if you’re concerned about how long a transfer is taking. If something feels off, it probably is.<\/p>\n
