dialogue: #Person1#: Hi. I'm here for flight 513 to New York but I thought I heard the paging system announce that it is canceled. Is that true?

  #Person1#: No way! I worked very hard so that I could leave on today's flight. Are there seats on another airline?
  #Person2#: It's possible. If you would like to book with another airline the line is right over there.
  #Person1#: You mean the line over there of about 200 people? !
  #Person2#: That's the one. It seems that everyone is anxious to get to New York tonight.
