Delta FC does offer Glenlivit but seem to be out of it a lot.
Does that refer to Glenliv
et 12, 15, 18, 21, or XXV?
I think the last Amtrak train I was on and bought liquor, only had Dewars for scotch, and Jim Beam (or something equally un-drinkable!) for bourbon. Learned my lesson, now I bring my own if I will be wanting a beverage.
In my experience typical spirits include Canadian Club, Jack Daniel's Black, Dewar's White, Absolut, Beefeater, and Bacardi. Not a single top-shelf option among them. But, as many have learned you can bring whatever you want so long as you know how to conduct yourself in the company of strangers. I enjoy drinking, but I do not enjoy giving drinkers a bad name, and I certainly don't want whats happening to smokers to happen to drinkers because we abused (or allowed others to abuse) our good fortune. Amtrak's rules are easy to understand but also miss the point entirely. The issue shouldn't be about where you bought your liquor from so much as how well you can handle yourself and how disruptive you are toward others.
In a previous era you could bring whatever you wanted aboard an aircraft and simply hand it over to the stewardess to pour. This allowed you to have the brand of your choice at a reasonable price while also allowing the airline to help prevent overindulgence. It was a responsible solution that was beneficial to all interested parties. Technically self-supplied liquor is still allowed by the FAA, but the airlines themselves would rather make it all about who does the selling than who does the actual drinking. Likewise, Amtrak will happily sell you more than enough to liquor to get completely plastered and even let you drink it whenever and wherever you please so long as you bought it from
them.
