Hi, Mark Davis here.
Hello Davis, how may I assist you today?
I would like to take my family at Washington in this winter vacation, can you please book a flight ticket for me from LAS to DCA?
Sure, can you please tell me your travel dates?
Sure, we will go on 01/17 and return on 11/19.
Sorry to inform you, there are no flights found with the dates you have provided.
Ok, no problem, we will go by another way. Thank you.
Thank you for your positive response. Have a nice day.
