The flight was mostly great, though the food was terrible and we were given so few drinks I became very dehydrated. The cabin crew were not seen for hours. Then on arrival in Dublin we were stranded on the runway for an hour then another 30 mins at the gate before someone attached the gangway. It was terrible
