Sorry, this is hard to search for so I figured I would post.

I am looking at a flight, ORD to BRU. Regardless of the ticket I book, the flight is operated by UA. It is substantially less expensive to book as a Continental Departure and a Brussels Airlines return ticket, still operated in both cases by UA.

I am wondering how MP works if I provide my MP number for this ticket, will I be earning MP miles at the UA rate (For Biz: 125% award miles + status bonus, 150% EQM + status bonus) or the Brussels Airline Rate (100% award miles + 125% EQM).

Long story short, is mileage earning based on metal or ticket?

Thanks.
