Due to mechanical, I was rerouted the other day from UA to NW.

My UA-issued NW ticket was issued in INVOL fare basis.

Now today, I checked my NW WorldPerks account, and although it lists my flights, no mileage credit has been posted yet...In the 'Reason not credited' area, it says something to the degree of 'Pending Internal Review' or something like that.

Any time in the past that I've been bumped, I've always received credit on both the carrier I was moved to as well as my originally scheduled carrier (usually UA and after filling out the form, sending in my ticket receipt along with fingerprints and blood sample)

Has something changed? I assume (and hope) that the mileage credit for these NW flights will appear in a few days. Anyone else have experience with being moved to NW and not getting the miles?
