Hi all, I'm sorry to have to ask, and I have tried writing to both CO and UA, but the emails they are answering for me today are literally questions I asked them 3 or 4 weeks ago. So while I can't get an "official" answer in print, I am wondering if perhaps I am missing something - but in my situation EVERY mile counts. I'm not concerned about upgrades, just calculation of miles. If I figured out one thing, its if you pick the wrong number to apply to your reservation, it's a world of hurt fixing it. Background: I am a 75K flyer from 2011, so I am Premier Executive on United, Platinum on Continental, will be Premier Platinum after the merger. I always fly the exact same itinerary. NAP-MUC (Operated by Lufthansa, 516 miles), MUC-IAD (Operated by United, 4267 miles), and then return IAD-MUC (Operated by United, 4267 miles), MUC-NAP (Sometimes operated by Air Dolomiti DBA Lufthansa, sometimes by Lufthansa). It is always a Y class ticket. Under 2011 rules, I always used my MP number (I was Premier Executive on OP, but only Gold at the time on OP), and was always getting 774 (516 x 1.5) EQMs for the NAP-MUC segment and 6401 (4267 x 1.5) EQMs for MUC-IAD, presumably because the flight was booked in Y class. I would also get 1032 RDMs for the NAP-MUC and 8534 RDMs for MUC-IAD, which I guess was the 100% bonus for being Premier Executive/Gold. So in sum, I was getting 14439 EQMs and 19132 RDMs per round trip. I do 7 round trips per year, so I make it to 1K by only about 1,000 miles so I have to do it right The questions (finally): Pre Merger: 1) From now until the official merger, given my situation, does it matter which account number I use? [Assuming they are still using 2011 rules, I would think I'd get the same 14439 EQM and 19132 RDM miles but my concern about using the MP number is that Continental specifically includes Air Dolomiti DBA Lufthansa, but MP does not, and one (I believe not so knowledgeable) MP agent said that Air Dolomiti doesn't get any credit.] 2) After the merger, when I go to 75% as a Premier Platinum, am I calculating it out correctly that I will still earn the same number of PQMs and RDMs, as Y is still supposed to carry 150% PQMs, and I think I read where my RDMs, while only 75% as a Platinum, there is an additional 25% non-PQM bonus for Y tickets? I am FAR FAR FAR less concerned about the RDM calculations as I am about the EQM/PQM calculations, and I truly appreciate your thoughts on my questions. I'm active duty stationed overseas so I can't call the 800 numbers and I don't want to call the direct number internationally as it is very expensive, and even then, one agent's opinion usually varies from the next's. Thanks again, and happy new year.
