hello
Hello, how can I help?
Hi, I need to reserve flight 181 under the name of Alexis.
Sorry, but the flight with id '181' is not available any more.
Oh no, is there something similar?
There's no other flights that I see available at this time unfortunately. 
Ok, I guess I will have to check another airline.
Is there anything else that I can do for you?
no thank you, goodbye
Thank you and goodbye.
