Hi.
Hello, how may I help you?
I need to book a ticket from DFW to IAH. Could you book a ticket?
Can you please share your trip dates?
Departure is Dec, 24 and return date is Dec, 26.
Do you have any other requirements?
I would like to return in the afternoon.
 Thanks for sharing your details, we are unable to provide flight in between your journey routes due to heavy snowfall at destination airport.
Thank you.
Thank you.
