Hi. I am Dorothy Taylor.
Hello, how may I help you today?
 I need your help in booking of a flight ticket from LGA to DCA for an important business meeting, can you please help me out with booking of a flight ticket on those locations?
Sure Taylor, may I know your dates of journey please?
My trip dates are 04/16 to 04/18.
Sorry Taylor, there is no flight found as per your travelling details.
No issue, thank you.
You are welcome.
