I do not know if this should be posted here or SLF (MODS PLEASE MOVE IF YOU THINK SO) but I was asked by my wife who recently flew with EK why the drink the Cosmopolitain is only available on US bound EK fights. I had no idea, and fly with EK quite a bit, but will not be with you again for 6 weeks or so, therefore I thought I would ask question here. Over to you in anticipation.
