Hello. I am Frank Roberts.
Hello, how may I guide you?
I planned to attend for a wedding in AUS, can you please help me to book a flight ticket from IAD?
Sure, can I know your preferable dates?
I prefer to travel on 07/06 and 07/08.
I am sorry, there are no flights available.
Ok, not an issue. Thank you for your infomation.
Thank you, have a good day.
