Hello. I am Andrew Davis.
Hello, how may I guide you?
I planned to attend for a wedding in DFW, can you please help me to book a flight ticket from DCA?
Sure, can I know your preferable dates?
I planned to travel on 12/19 and 12/21. Please make sure that the connection is 0.
 found a flight 1004 of Frontier airlines matches with your preferences, can I proceed?
Ok, please confirm my booking.
Your ticket is booked.
Thank you for your help.
Thank you, have a good day.
