It is a budget airlines and it feels like it. Cheap, but between us and our neighbors, one charger didn't work, one seat wouldn't lock and would collapse on the people behind us, and two food trays didn't lock in place well. It wasn't that big a deal - we just handled the fixtures carefully, but you get what you pay for.
