Hello, Catherine Robinson here.
Hello Catherine. How can I help you today?
I planned to attend for a birthday party in LGA, can you please book a flight ticket from IAH?
Ok, when you are going to start your journey?
I prefer to travel on 06/16 and 06/18.
Ok, wait for a moment please. Sorry to say this Catherine, no flights as per your details.
Ok, no problem.
Anything else to help you.
Thank you for your information.
It's my pleasure, have a nice day.
