Thanks for all the help on this. I guess I will value the miles at the marginal cost of the C ticket to me, $1,500 + 2 SWUs, $.015 per mile. An SWU is of little value because I travel on upgradable fares once or twice a year, so I have left overs usually. I'll book the W fare and use SWUs. Status has me worried this year, so I'll take the EQMs.

I am worried about miles devaluation too. The lack of available C space has me scared. This is the first time I've found C space somewhere I want to go + or - a month of when I want to go.
