I can't see them eliminating free upgrades. They've already ticked off enough people by eliminating JFK routes to the west coast from upgrades. As a diamond not on a discount fare this weekend dtw/lax it doesn't look like I'll clear either way (only 1 seat in first on Friday), and it's not like the short haul upgrades are costing them anything. I could see them going with a sticker system like American has for silver and gold's.

I wouldn't be surprised to see MQM rollover's being limited. If that happens though I will consider using Amtrak or driving on my Chicago trips instead of using Delta
