I am a Platinum Medallion on DL. I (usually) have no trouble reaching DL quickly and efficiently on the DL elite reservation lines. But when it comes time to have to call another ST carrier, I have no access to any special reservation lines.

It would be a good idea if the ST carriers each had a separate res line for the elite members of the other carriers in ST! Obviously, those are folks who fly a lot, and it wouldn't hurt business to have an easier way to talk to a reservation agent.
