Hi.
Hello, how may I benefit you?
As I am a arts student, I actually made a plane reservation to  Detroit earlier for submitting my project report in Detroit institute of arts but now my project is still pending and I need some time to complete it. So I want to change my existing reservation.
Certainly, I can help you in doing that.
Thank you.
Could you please let me know on what name your reservation was made previously?
 Please check the reservation by the name Emily Davis.
Ok, please give me a minute. I will get back to you.
Ok.
Thanks for your time, I have gone through the reservation list but could not find any reservation by the name you provided.
No issue, Thanks for assisting me.
You are welcome. We hope to serve you again in future.
