The title doesn't quite capture the whole question. My question refers to the DL Connection (various carriers) and their policy ref. pre-departure beverages. Most of the time, if there is a FC cabin, pre-departure drinks are offered, the same as would be true on mainline DL flights.
However, on mainline DL, you always have the option of alcoholic drinks. This is also true on some DL Connection flights. Yet, on some carriers, alcohol is only available in the air. I know in some cases it could be a local law, but for example ATL or MKE I've seen some Connection flights NOT offer alcohol on the ground, where other Connection carriers and DL mainline do.
My question is why? Is this a tax or licensing issue? Or is this a policy related to the carrier?
Thanks for insight!
