Hi. Jacob Anderson here.
Hello, how may I guide you?
Can you book a ticket from DCA to PHL?
Sure, can I know your preferable dates?
I would like to travel 12/02 and 12/04.
 I found a flight 1015 of Delta airlines matches with your preferences, can I proceed?
Please proceed with it.
Your ticket is booked.
Thank you so much.
Thank you.
