Im trying to remember what I got out of Europe when I was on UA, I dont remember it being KA, but I usually didnt fly UA to/from Europe I usually use my Miles for European tkts and flew whomever out of JFK
Out of Europe I believe its gonna be the local caterer which isnt teh case with Asia but is with SYD/MEL
AC ex YYZ was Hamasbia as expected. taste was good. (chicken rice, omelette)
AC ex NRT was Unger catering. taste slightly below average. (grilled fish and smoke salmon, corn omelette)
