Not while flying, but in many, many sea ports. Worst beer ever is in Italy, Peroni. Yuk and instant splitting headache. All the rest are just beer. After the third one, they all taste the same except for stouts. Also found, much to my dismay that beer is a great contributor to GOUT. Yep, that and wine, aspirin and red meat. Guess what is no longer in my diet. And of course the old saw, "one does not buy beer, but merely rents it."
