Hi.
Hello. How may I help you?
I want to change my reservation as I want to stay for some more days with my friend at Houston. Can you please do that for me?
Sure, I am here to help you. May I know your name to check your reservation?

Please wait a moment, let me check your reservation.

Sorry to say, there is no reservation found with your name to change it.
No problem, thank you for checking.
Thanks for choosing us, have a good day.
