I wasn’t sure how Delta Amex upgrade offers worked until I actually received one on a long-haul flight last year. I had the Delta SkyMiles Amex card and got a targeted email offering an upgrade for a modest fee or miles before my trip. Since I wasn’t sure how to apply it, I called 8 8 8-2 1 7-3 3 2 4 while booking. The agent explained that these offers are usually sent to select cardmembers and let you move into Comfort+ or even First Class if seats are available. They helped me apply the offer and confirmed everything, which made me feel confident I wasn’t making a mistake. Later, when my travel dates changed, using the same number to modify the reservation and check how the upgrade offer moved over was super easy. From my experience, Delta Amex upgrade offers can be a great way to enjoy a nicer seat without the usual stress of award upgrades!
