Well, yes, to Comfort+ assuming that they book early. However, I don't think that that is what you meant... With F purchases in strong demand, F upgrades for Diamonds are few and far between, depending on the route and day/time of day. I think that most Diamonds have a less-than-50% F upgrade score these days, and that is not going to improve much in the new system (many Diamonds have a lot of MQMs saved up and will continue to be Diamond for years at 100K MQM/year).
