Hi.
Hello, how may I oblige you today?
I am Nicole Lopez. I would like to book a ticket from DCA to HOU, can you help me?
Sure, can you please share your journey dates that you prefer to travel?
My travel dates are 01/08 and 01/10.
 Thanks for sharing your details, we are unable to provide flight in between your journey routes due to heavy snowfall at destination airport.
No problem, thanks for checking.
 Your welcome.
