documents: #Person1#: Hello, this is South Airlines. May I help you?
  #Person2#: Yes, please. Mrs. Dick booked a ticket for Fight No. 112 to New York at 9:00 tonight. I'm afraid it's difficult for her to take it at that time. Is there a later fight tonight?

  #Person2#: That's right. Please help me to call it off.
  #Person1#: OK. And here's another flight, No. 211, at twenty to twelve. Is it OK?
  #Person2#: That's fine. Please book a ticket for this one.
  #Person1#: All right. Call off the ticket for Fight No. 112 and book one seat on Fight No. 211 to New York.
  #Person2#: Flight No. 211 to New York at twenty to twelve. That's perfect. Mrs. Dick will pick up the ticket at the airport herself.
  #Person1#: Good. But please remember it must not be collected later than 11:10, and I need to check the ID card.
  #Person2#: I'm sure she will do it by the time. I'll remind her. Thanks.
  #Person1#: You are welcome.
