Hello, I am Debra Martin.
Hello, how may I help you at this  moment?
As my manager did not approve my leave, I would like to change my existing reservation.
Please share your nearby airport codes.
My source and destination airport codes are MCO and MSP.
Can I have your travelling dates?
I would like to go on 02/10 and return back on 02/12.
Please wait for a moment.
Ok, ensure it is a single connecting flight.
Southwest airlines is providing 1 connection flight and its cost is only 100. Shall I book it?
Ok, please proceed for further.
Your booking is done with flight number 1015. Have a nice day.
Thank you for booking.
Welcome. Thank you for reaching us.
