Hi.
Hello. How may I guide you today?
I am Kathleen Taylor, can you help me for changing my existing reservation, because in my previous reservation I gave wrong airport codes?
Sure, I will help you with that.
Thank you.
Please give me  a minute.
Ok, I will wait for your reply.
I am sorry to say that there is no reservation found under your name.
Oh! It's ok, I think my sister already changed my reservation.
Thank you for contacting us, have a great day.
