I'm one of those that racks up 100k+ MQM a year on primarily LUT fares (maybe a rare K fare here or there) and credit card spend. So, if and when this goes into effect, there's a very good chance I'll move to AA. Here's my question though:
Would it be better to:
(A) Go for DM this year so that I can continue to fly DL in 2013 as a DM and then leverage my DL DM status for *hopefully* an AA EXP PLAT match or challenge into 2014?
or
(B) Stay at PM with significant roll over so that I can continue to fly DL in 2013 as a PM and, with all that roll over, still probably make enough MQM (even under the new fare-based earning rules) to make PM again for 2014?
With option (A), I get to stick with DL through 2013 and will have a better chance of matching to a competitor at a higher level for 2014. With (B) I get to stick with DL through 2014, but my chance of matching to a competitor at their highest level is reduced for 2015.
