I'm using a bulk airfare booked on LH to travel from EWR to TIA and return from SOF. I'm told I can use my UA Mileage Plus Number for the trip, but because it is an unpublished fare, mileage accrual is at a reduced rate. The booking class is Q, but I'm not sure of the fare basis.

Any idea out there as to how much mileage is credited for such flights?

Thanks!
