I think UA has stepped down a class or 2 on most of their liquors, and specifically with the Scotch, the Chivas and Dewar's offerings that they had are now only the cheaper Dewar's (with the addition of the Glenlivit in C and F internationally, sometimes).
iluv2fly posted a link to the current Hemispheres issue and it says Chivas is still served. I don't know much about scotch.
