I was on my Southwest flight recently and noticed this ad on the back of the drink menu:
You can show this picture and get a free wine, beer or well drink only at New York New York in Vegas at Pour 24, Center Bar, Nine Fine Irishman, or Lobby Bar. Valid until 12/31/14.
If you are in the area then go get your free drink! Its hard to see but the code is 199108809
Heading to Vegas tomorrow, thanks for the tip!
Let me know how it goes!
If this actually works, I recommend going to Nine Fine Irishmen and pouring your own glass of Guinness.
