My name is Alina and I want to reserve flight 276. I want this done QUICKLY - thank you.
Sorry, but the flight with id '276' is not available any more.
What is wrong with you!? It was available just a minute ago.
Is there anything else that I can do for you?
Change it 821 and see if I can get that flight.
The flight is available. Should I reserve it for you?
Yes.
Right, your flight is now reserved!
Bye,
Thank you and goodbye.
