Hello.
Hello, do you need any help from us?
Myself Dorothy Edwards, I need you to book a flight ticket form SEA to IAD.
Sure, could you please share your departure and arrival day?
October 19 and 21 are my travel dates.
The economy class with flight number 1004 is available, is it ok for you?
Please make sure that the flight departs in the afternoon.
The Spirit airline with flight number 1020 is available, is it ok for you?
If it is a connecting flight please book the ticket.
Ok, your reservation is confirmed.
Thank you for the help.
You are welcome, have a great day.
