Hi.
Hello.
Lisa Robinson here.
How may I assist you today?
I heard very great about National Mall at Washington that it has many museums and monuments over there to visit, I am planning to visit that place. Please help me to book a ticket from SEA to IAD.
That's good to hear Lisa, which dates that your are planning to travel?
I am planning to travel on 03/26 and 03/28.
Ok, wait for a moment to search for  flights. Based on your request there is a flight 1021 with a fare of 200, is it ok for you to travel?
Yes, please proceed for booking.
Lisa, your ticket has confirmed with Spirit airlines.
Thank you for the help.
Enjoy your trip Lisa, happy journey.
