不好意思，我能不能和別人換一下座位呢？我想和我老婆坐在一起。
FLIGHT ATTENDANT: Certainly, sir. For now, please take your seat, and once the plane takes off, I'll help you with that.
沒問題，先生。現在您先坐，等飛機起飛后我幫您換。
YOU: Thank you. Could you help me put this bag in the overhead compartment?
謝謝。能幫我把包放到行李架上嗎？
FLIGHT ATTENDANT: Sure. There you go.
沒問題，好了。

2.發現別人坐了你的位置
YOU: I'm sorry, I think you're in my seat.
不好意思，我想你是坐錯位置了。
OTHER PASSENGER: Oh, let me check my boarding pass. Yes, I'm sorry, my mistake.
噢，我看看登機牌。是的，抱歉，我的錯。
YOU: No problem. That happens.
沒事，這挺正常。
