SkyTeam - Delta/NWA credit for Aeromexico "webfare"

I see a "webfare" on Travelocity (and Priceline) on Aeromexico NY-PVR. Wondering if I can get miles for this. Delta site says "Mileage credit is not applicable for fares booked in G, I, O, P, C, E, F, U, W, or Z class" on Aeromex.

I can not seem to find a description of these class codes.

Travelocity rep says he does not know the class code but when I book it will be available. (um.. I want to know if I can get miles BEFORE I purchase the ticket).

Anyone ever get a "webfare" on Travelocity (or Priceline) and know if the fare code is eligible for mileage accrual?

probably not. You need the fare class to be certain. Check Expedia or ita for fare classes.

At some point in the booking process you should be able to find the fare rules. The rules rules should have the fare basis defined, the first letter of which is the one you want to match to the DL details.
