Is it possible to earn points and get Gold-level benefits on bookings made through Expedia? I was under the impression that the only bookings that don't earn are the opaque bookings, like Hotwire-type deals. I'm trying to get the HH agent to add my HH # to a reservation, but they're telling me that they can't change it and I won't earn points. Is this right? Expedia says they're also unable to add my HH #.
