Hi, this is Emily Taylor.
Hi, Emily.  How can I help you today?
I need to book a flight to attend my sister's wedding in AUS.
Okay.  Where will you be departing from?
I'll be lea  ving from LGA.
When do you plan to make this trip?
I want to fly there on 05/01 and come back on 05/03.
Okay.  Do you have any preferences regarding the airline?
No, as long as it doesn't cost more than 200, it will be fine.
There's a flight that matches your criteria for 100 on AA.  Will that work?
Sounds good, please book that for me.
Your flight has been booked.  Please give us a call back if you require any further assistance.
Thanks for your help.
Your welcome and have a great flight.
