Hi.
Hello, how can I provide assistance for you?
I am Larry Hernandez, due to my health issues I would like to change my recent reservation which I have done last week to Denver. Can you help me to change my existing reservation?
Sure, please wait for a moment to check your reservation status in my records.
Ok, I will wait for your response, but get back with my reservation status.
Sorry to say, I did not found any reservation status under your name in my records.
Oh! It's ok, I think my sister already chenged my reservation, anyway thank you for your services.
Thank you for choosing us, hope we will get an opportunity to serve you in future.
