Hello.
Hello. How may I aid you?
I am Paul Gonzalez, want to travel from ORD to SFO. Please help me in booking my ticket.
Sure, can you please specify me your dates of travel?
My travelling dates are from 11/07 to 11/09.
Would you like to travel in an economy class or in a business class?
There is no particular class preference.
 Is there any another specifications on your trip, so that I can arrange like that only.
My departing time should be in the evening and my airline preference is normal cost.
Sorry, we don't have any flight available for your trip.
It's ok, thank you for your help.
Thanks for consulting us.
