Hello.
 Hello, how may I oblige you today?
I am Helen Thomas. I would like to book a ticket from SEA to IAH, can you please help me out?
Sure, can you please share your journey dates that you prefer to travel?
I am travelling on these dates OCT 23rd and 25th.
Do you have any other requirements?
I prefer departure time in the evening.
 Thanks for sharing your details, we are unable to provide flight in between your journey routes due to heavy snowfall at destination airport.
Ok no problem, thank you for your services.
