Hello.
Hello, how may I aid you?
I want to book a flight ticket from Dallas to attend a client meeting in Washington , can you help me to book a flight ticket with single connection?
Sure, may I know your trip dates?
10/17 and 10/19 are my planned trip dates.
Do you require any stopovers in your journey?
I already mentioned above.
Do you have any other requirements?
I want to depart in the evening.
Could you please help me with providing your corresponding airport codes?
My boarding and landing airport codes are DFW and DCA.
 Thanks for sharing your details, we are unable to provide flight in between your journey routes due to heavy snowfall at destination airport.
No issues, I'll choose any alternative. Thank you.
Please share your name?
I am Betty Baker.
Thank you.
