Hello. Pamela Lopez here.
Hello Lopez, welcome to Global booking agency. How may I aid you today?
I would like to visit IAD, so can you help me booking flight from IAH?
Sure, I will help you. When would you like to departure on?
My travel starts on  09/15 to 09/17. Make sure with 0 connection.
Ok, please be on hold for a moment to check the availability of flights.
Ok.
Sorry Lopez, there are no flights found with your requested dates of travelling.
Ok, that's fine. Thank you for your services.
Thank you for reaching us, have a nice day.
