Hi. I am Richard Johnson.
Hello. How can I help you?
Please search flights on these airport codes DEN to LGA to attend my dance event?
Sure, please tell me your travelling dates.
My travelling dates are 11/10 and 11/12.
Sorry, all flight tickets are sold out in your requested month.
Oh! That's really sad to hear this, ok I will complete my journey in another way. Thank you for your services.
My pleasure, thank you for opting us.
