They didn't come and offer snack boxes for sale? Your claim of "no food service" seems to suggest it, but I've never not been offered a snackbox for sale on the longer ERJ flights. If no snack box sales, that is pretty bad. If nothing other than snack boxes, this is SOP for UAX and isn't a recent change, and as a 1K, this shouldn't really be a surprise. If you wanted a meal flight, should have booked a mainline.

But I do agree, they should probably change the food service on the longer ERJ segments and at least offer some of the non-warmed options for sale in Y, and a cold plate in F.

As to the actual thread topic, I've never been on a UAX where they were dry - they always have had alcohol when I've asked (though I admit - I don't drink too much on UAX flights since they are usually ~1 hour or less flights for me). I know they won't do alcoholic PDB ex-Canada because of local laws, and I've seen them run out at times, but never not have any.

I doubt they've changed to not have alcohol on UAX flights either - if UAX was all short flights, I could see it happening, but with the longer lengths of some and the ability to make $ off of it, something I can't imagine they'd take out. My guess is either you had bad luck with flights being mis-catered (or possibly ran out when returning from the outstation), or potentially a carrier-specific licensing issue that needs to be resolved (i.e. license didn't get renewed on time for whatever reason).
