I was once a big advocate of getting people on the aircraft via the jumpseat. But now having endured two ULH sectors as a PX crew and their being F class seats available and not being upgraded by ISM. Those days have come to a end. Tired of helping cabin crew who have no problem spitting in your face when a favor is hoped for. After flying for many airlines. I find the crew at CX to be the most disappointing. A culture of ugly. Make fun of US airlines and their fat FA's. But they are far more stand up then ours. They look after a brother or sister. At the end of the day. That's what matters to me. Why we can't all get along and play nice. I will never understand.
