Serving with plastic cups just seems to be faster. Also consider that many times pre-departure beverages are served while lots of economy people are floating through the domestic F or Int'l C cabin, unless they board through door 2 like on the ever rarer 757. Ma and Pa Kettle in Boarding Group 4 or 5 bumping into you with their 22" carry on checked bag replacement is unpleasant enough, imagine them knocking over glassware on top of that. Or the F/A with their little tray bumping into someone.
Much less likely to happen in flight since a curtain is drawn and traffic in the premium cabin tends to not have the same godawful restroom lines that cause headaches to whoever works the rear galley and tries to get a service cart from there to the curtain and back. As an added side effect, perhaps it will also reduce the envy of those who pass through during boarding, although domestic first is certainly attainable price wise for pretty much anyone who flies today.
It's just a question of whether they want to trade 5 hours of relative comfort (Denny's style food on real plates vs. snack box, yay) for 2-3 days of their travel budget. If it's any consolation, more and more premium BoB products (e.g. Half bottles of drinkable wine, Moscow Mule on UA
) are coming online, pretty sure that will continue to move towards including glass and china (e.g. LH
premium economy) even in the U.S. as the various Y+ products continue their evolution beyond the extra legroom. With F on the way out, U.S. airlines are actively contemplating the future of Y+ as a separate class of travel taking the spot that used to be held by C cabin 15 years ago.
From a product perspective, I'd rather have champagne in a plastic cup than sparking wine in a glass. Much like I'd rather have a wider seat or flatbed than eurobusiness middle seat seat blocked. I gladly drink out of a plastic cup during pre-departure in return.
If it really upsets you, just bring some glassware from the club onto the plane, wait for your beverage to arrive, pour it into glassware, and then return the glass to the F/A as s/he collects the plastic cups. It's not theft since you're returning the glass to the company, and it should make for an interesting flight with the F/A as s/he starts paying attention to the cloth serviettes and the glassware issued to you during the remainder of your trip
