Hi. Emma Collins here.
Hello. How may I assist you today?
I want to attend my sports events, so can you help me booking flight from DCA to PHX?
Sure, on which dates you want to travel?
My travel starts from 06/21 to 06/23.
Please wait for a minute.
Provide flight  with connection 1.
I found a flight with airline AA which is exactly matched with you criteria.
Ok, proceed to booking that flight.
Your ticket has been booked with flight number 1019.
Thank you for your services.
It's my pleasure.
