Hello.
Hello, how may I help you?
I am Nancy Davis. Please help me in booking a flight ticket from DFW to LGA.
Sure, can you please let me know your travelling dates?
07/19 and 07/21 are my preferable travel dates.
Do you require any specifications in your journey?
I need a connecting flight and my depart time should be at morning.
Do you have any airline preference?
No.
 Thanks for sharing your details, we are unable to provide flight in between your journey routes due to heavy snowfall at destination airport.
Ok, not a problem.
Thank you.
