First, I admit that English is not my first language. No matter how many times I read the T&C on United.com, I am not 100% sure how the PQMs are supposed to work for flights marketed by Star Alliance members. Here are a few snippets from MileagePlus page for Brussels Airlines: 1. "Earn MileagePlus® miles on all qualifying Brussels Airlines flights, except as noted in the chart below. You’ll earn miles according to the booking class that you purchase." 2. "The miles you earn on Brussels Airlines qualify toward MileagePlus Premier® status, with 50% bonus MileagePlus Premier qualifying miles for paid first, business or full-fare economy tickets." 3. "If you purchase a ticket on a flight that is marketed by Brussels Airlines but operated by another airline (known as a codeshare flight), the operating airline determines how many miles you earn for your flight." On a recent trip, I flew on Brussels marketed flights - one operated by 9W(Jet Airways) and another operated by UA. When I purchased the award accelerator option prior to the trip, I got the full quota of miles (19,032). But, after finishing the trip, I have not seen either award miles or PQMs for just one flight in my itinerary (SN4134) which was booked in S class. To give you guys an idea. The trip had a mix of UA marketed flights operated by UA & LH, and two SN marketed flights (1 by UA and 1 by 9W). This is on the same eTicket, everything visible on my United account with the confirmation #. This trip was completed on 9/25. So, what do you guys think is going to happen? (a) I will get award miles only on SN4134 because it is operated by 9W? (b) I will get both award miles and PQMs for SN4134? (c) Tough luck, I won't get anything. I have two upcoming trips to SFO(this weekend) and LAS (next month), and I am trying to decide if should go for UA or A3 to hit Silver status. I prefer getting UA silver status because it lets me pick E+ for free at Check-in. But, if I am not going to get PQMs for my SN4134 flight, I will credit my next two flights to A3 to get at least *A silver status.
