ASSISTANT: Hello, welcome to Easy Booking agency. How may I assist you?

USER: Due to an emergency, I want to travel in a direct flight.

ASSISTANT: Ok, but from where and to which destination you need to travel please share the airport codes.

USER: Source airport code is ORD and destination airport code is HOU.

ASSISTANT: On which date you want the tickets to be booked?

USER: The travel dates are from 05/21 to 05/23.

ASSISTANT: One moment, let me check the availability of flights on those days.

USER: Ok sure.

ASSISTANT: Thank you for waiting, there is one flight available but it is a connected flight, would you like to travel in this flight?

USER: Sorry, I need a 0 connection flight.

ASSISTANT: Sorry, there is no direct flights found in this route, as for the airports you are looking for those not so busiest airports, so all of the airlines prefer connected airlines to increase the flow of the passengers.

USER: That's fine, thank you for your help.

ASSISTANT: Thank you for opting us.
