Hello.
Hello. How can I assist you now?
I am Thomas Parker. Can you please assist me in flight ticket booking process from PHL to AUS?
Sure, I am happy to help you with that.  Can I have your travel dates please?
Thank you, I want to take off on Feb 03 and please confirm my return ticket also on Feb 05.
Ok, please wait a moment.
Ok.
Sorry Thomas Parker, no flight is available to you on your dates.
Oh! It's ok no problem. Thank you for your information.
Thank you for choosing us, have a good day.
