[speaker001:] Excuse me. Can I change my seat with you? I want to sit beside my friend.
[speaker002:] Where is your seat?
[speaker001:] It's 9 A in the middle part, a window seat too.
[speaker002:] OK, you mean the vacant one on the left?
[speaker001:] Yes, it is. Thank you very much. Let me help you to carry your baggage there.
[speaker002:] No need. I have only this small handbag with me.
[speaker001:] Thanks. Have a nice trip.
