Not true. I have a flight in February that would earn 9,505 EQM under a revenue model but 22,807 EQM under the 2025 COS model. No matter which option I chose, I'm giving up more than 50% of the miles I would have earned under the 2025 COS rules. This will not be an exception, but the rule. It completely changes the calculus of what airline I will chose to purchase tickets through and credit flights. Just because the new plan will be based on revenue, doesn't mean it'll be a good deal for those who buy expensive plane tickets.

In any event, we still don't know all the rules for the new regime and when they will be implemented, so there's no point trying to make any final decisions right now.
