Per Delta Points, Delta is taking away Platinum Medallion upgrades on Transon routes between New York (JFK) and Los Angeles and San Francisco for Platinum Medallions. This means that the only people who will be added to the upgrade list on these routes will be Diamond Medallions on paid fare with no companions in the reservation.
Delta Negative Transcon Upgrade Devaluation for Platinums Medallions
Delta is really devaluing their “loyal Medallions”. If you are a Platinum Medallion consider yourself no long a high value customer, as you’ll no longer be getting upgrades on transcons.
In other news however, Delta is downgrading their New York-Seattle flights to regular domestic planes (think 737’s) and because of this they are bringing back Medallion upgrades on this route. I don’t think this is anything special, but it’s worth mentioning.
