Hi.
Hello, how can I assist you?
I want to reach Houston on Sept 21 but previously I made a reservation on Sept 20, so I need to change my travelling dates. Can you help me with this?
Sure, may I know your name?
I made a reservation by this name Nancy Carter.
Ok, please wait a minute.
Sure.
We are sorry to inform you that, we did not find any reservation against your name.
That's fine, thank you for your information.
Thank you for reaching us.
