I finally treated myself to a Delta One seat for my honeymoon last year, and it was a total game-changer. I’ve found that the best way to snag that upgrade without paying full price is to keep a close eye on the Delta app right after booking.
About two weeks before my flight, a "Global Upgrade Certificate" offer popped up, but I actually preferred calling a representative to modify my existing reservation using my SkyMiles. The agent was great—they found a hidden seat opening that wasn't showing online yet. It definitely pays to be proactive!
Would you like me to write a version focused specifically on using Medallion Status or one for last-minute gate upgrades?
