Hi. I am Karen Green.
Hello, karen. How can I help you now?
Can you please change my existing reservation? Because my sister reserved me a ticket with a wrong airport and location.
Sure, I will help you with that.
Ok.
Sorry Karen, there is no reservation found on your name.
No issues, thank you for checking.
Do you have any other dates to travel?
No, I didn't plan yet.
Ok, thank you for approaching us. Have a great day.
