Also useful if you have somewhere to fly on an economy ticket. Noteworthy is that often the alcohol is free, along with the food. Having flown business on a couple of trips I can tell you with 100% certainty that I'd rather wait in the lounge than out at the gates. Because, beds & showers.

FWIW, Emirates has free Alcohol on their flights for economy passengers. Don't know about the selection as I tend to sleep most of the flight, but they have at least red & white wine and Jack Daniels.
