Hello, how may I serve you?
assistant
Can you please change my existing reservation? Because I booked a direct flight instead of connecting flight.
user
Sure, I can help you with that. Can I have your name to check your details in reservation list?
assistant
Ok, I am Matthew Garcia.

assistant
Sure.
