I completed a mileage run late last year (LAX-MSP-ANC-MSP-LAX) to make PM but I am still fairly new to mileage runs and this is my first post about one so be gentle, haha! I am shooting to crack DM this year and was unable to rollover much of anything as I just became a SkyMiles member in August. I've already booked the LAX-MIA run Delta Point's Rene posted and I figured I'd post this one to share and get feedback as to whether or not it looks like a worthwhile deal.
It's also worth noting that for $884 (7.2 cpm) you can book the entire run in business elite to earn 12,214 MQM. This might be good if looking to bank more MQM in one sitting and/or for those folks not looking to leave the direct LAX - JFK (vise versa) upgrades to chance. Certainly a better deal than paying $995 to Delta for $10,000 MQM IMHO, although it obviously won't combine with qualifying miles from the 2012 calendar year like buying MQM before 1/31 will.
