Hi. Emily Lewis here.
Hello, how may I serve you at this moment?
I am looking for a flight ticket with morning as the depart time. So can you book it for me?
Sure, I will help you. Please send your trip dates.
The travel dates are from  22 June to 24 June.
May I have your source and destination airport codes respectively?

Sorry, there is no flight available on your requested dates.
That is not a problem. Thank you.
