Flew on the A380 three times in a week on long haul flights. Food and services were usually good, only on one occasion I waited nearly an hour for dinner. There were seats facing backward and I felt awkward when the passenger seating the opposite side stood up while I was in a totally unprepared state.
I changed my connecting flight at Abu Dhabi airport. The airport was busy with many passengers and business lounge was usually packed. Washroom facilities in the lounge were not enough and there were always queues outside the washroom. I waited for 35 minutes to get a shower.
