Hi.
Hello. How can I help you today?
I would like to change my flight reservation as I am unwell. Can you please help me?
Sure, I will help you with that. Please mention your name.
The reservation was done in the name of James Lewis.
OK, please wait for a while.
Sure.
Sorry Lewis, no reservation found by your name in our database.
Not an issue, thank you so much for checking.
