Blast it. My name is Ben and I need to reserve flight ID 433.
Sorry, but the flight with id '433' is not available any more.
What the heck. I can't believe this.
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
Actually the flight ID is 318. Urgh.
Sorry, but the flight with id '318' is not available any more.
Nevermind.
Is there anything else that I can do for you?
