Hi.
Hello, what help that I can aid you at this moment?
I am David Smith, can you help me to change my reservation to next week?
Sure, I will help you. Please give me a moment to check it in our previous reservation list.
Sure, please check.
Thank you for your patience, I have checked based on your request but it is showing that no flight ticket has booked under the name that you have mentioned us for checking purpose.
Oh! ok, no issues. Thank you for your time.
It's my pleasure and have a great day. Thank you for reaching us.
