answer: #Person1# and #Person2# are on board. They find their seats and change the seats. Then they put their luggage on the overhead compartment.
documents: #Person1#: finally we're on board!
  #Person2#: yes. It was so crowded. I'm worn-out. Let's find our seats.
  #Person1#: are they window seats or aisle seats?
  #Person2#: let me see. . . yes, one window seat and one aisle seat.
  #Person1#: ok. But can I trade my seat with you? I prefer the one near the window. I'm a terrible flyer. I always get airsick and can never relax until after I've landed.
  #Person2#: that's fine. I'd like to be on the aisle anyway. It's easier to get in and out.
  #Person1#: thanks. Where shall we put our luggage?
  #Person2#: I think the smaller carry-on bag can go in the overhead compartment, and the others can go under the seat.
  #Person1#: good idea.
  #Person2#: don't forget to keep the seat belt on.
  #Person1#: ok. Hope it's a pleasant trip.
  #Person2#: yes!
  #Person1#: and no hijackers.
  #Person2#: oh, you have too wild of an imagination.
