>>If you go to DM you won't get two Choice Benefits in 2014 and 2015 -- only two in 2014.

Why wouldn't I get two in 2015?
I make DM in December, I will be able to choose 2 Choice Benefits (thats 2 for 2014).
In Feb (I think thats the time period), you are now allowed to choose the 2015 Choice Benefits (so thats 2 in 2015)

Right?

>>As for more bonus miles, with SM2015 you'll get 2 extra miles per MQD, so estimate your MQDs for 2015 to see how much extra you'll earn.

No idea on travel for 2015.

>>Your estimate of Gold in 2106 if you hold short is only valid if you make the MQDs in 2015

You are right, I didn't think of it this way. (I think thats what fromYXU was referring to, but I didn't GET IT until just now)
I always was able to get enough MQDs because MQDs usually do equal the miles flown (if you buy a "normal" priced ticket) -
But if I roll over 50k miles, if I end up not flying...then I would not have the Gold level MQD, so I wouldn't be able to get Gold status anyway.
Is this what you are saying?

If thats the case, then I might as well get Diamond, because rolling over miles is worthless, because I won't have the equivalent MQDs (I only get MQDs from flights, and my company wants us to book cheap tickets)

Thanks
