SYD - PER

These economy class seats must be as cramped as they can possibly get? It's almost impossible for two adults to sit next to each other. The blonde Australian air hostess at the back was rude. Despite Qantas' bad service overall I've now had a few experiences where the attitude of the team on board just makes up for their flights always being late. This was not one of those flights. The ice cream is a nice touch!
