Old Fashioned International Mileage Upgrade vs the Seat Map upgrade
Just booked the four of us in PS to ICN next Oct 2024 on Delta. I want to use miles to upgrade- the Old Fashioned International Mileage Upgrade to Delta One- Not the Seat Map upgrade - I called and surprisedly the rep knew what I was talking about (I think) and said those are a complete different bucket of inventory- and that it probably won’t open until the summer. Has anyone had experience with these? I have co-workers who did this over the summer and their upgrades cleared really fast!!!
Thoughts? Ideas?
