I am booking a complicated international itinerary. The ticket is issued on Delta ticket stock, with 6 flights on Delta, KLM, AF and Croatian airlines metal, and flights with Delta, KLM and AF flight numbers. All is in business class, but several fare basis's are used, including J, D and I. Before booking I wanted to know the MQMs, since I am concerned about re-qualifying for Platinum and possibly Diamond. I spoke with 3 agents at Delta, including 2 supervisors and asked them to calculate the MQMs. I got three dramatically different numbers, with differences as great as 10,000 MQMs. And no one was willing to put their calculation in into the record. The bottom line was that they indicated that after I purchase and fly, I'll find out how may MQMs. (All of this is to say nothing of the potential confusion about earned miles and MQDs.) I find this unacceptable as frankly in part I decide on my choice of carrier based on qualifying for elite status. (I really don't care about the actual miles, since they are increasingly useless.) Tangentially, I have gold (one-world emerald status) with BA as well, and thank goodness their calculation of tier points for qualifying for elite status is still simple. Does anyone know where and from whom I can get unambiguous MQMs calculations. Again, this is simple for flights on Delta or those booked on Delta.com. But the itinerary I am interested in cannot be booked on Delta.com.
