How may I help you?

Actually, I booked a ticket to attend a music concert in LAX but due to bad weather the concert is postponed, so I want to postpone my trip.

Ok, so would you like me to change your existing reservation?

Yes, can you help me out?

Sorry, I could not find any reservation done with your name.

Thank you for your time.
