bmi diamond club - UA A booking code with Q fare.

So a while ago I purchase a trip on United that I have coming up. At the time of purchase I bought an economy fare, but before purchase was finalized United gave me a "premium seating offer" which I took. Looking at the reservation it has a booking code of A, so not NF. I'm thinking of crediting this to my BMI account but am wondering if I'll receive the 3x miles or not.

Thoughts?

Anyway you can check the fare basis?

I am thinking that a Q fare that books into A (first) is a Q-UP and will indeed attract 300% miles in DC

The fare basis is QA, not a Q-UP (I buy lots of those), when I booked this I wasn't searching for discounted F on UA, but Economy. It was after I had put in all my CC details that UA.com offered me the "Premium Seating Offer" for XXX dollars more it would confirm me in F. I took the offer and the Booking class became A instead of Q, but the fare basis remained QA.

It is the booking class that matters. If it is truly going to post as an A-class sector then you should get the 300%.
