Hi.
Hello, how can I help you?
Brian Wright here. I have planned a trip with my students to enjoy the holidays in water world in the month of March, so please book an advance flight ticket for me to DTW from my home town MSP?
May I know your desired travel dates please?
Thank you for taking my request into consideration. I am planning to leave my location on 03/28 and please book my return ticket also on 03/30.
Please wait a while. I will check and inform you.
Ok.
Sorry to say, there is no flight on your desired travel dates.
 Not a problem but I have expected a lot about your agency that I can get a flight for my journey. Anyways I will go with another agency, thank you for the information which is provided by you.
Our agency is one of the best agency as you said, if we cannot find a flight for you, no agency can provide a flight for you on your desired travel dates. Anyway, thank you for opting us.
So many agencies are there in our area with better services.
Thank you for choosing us.
