Hi, I'm trying to book a flight from New York City to Puerto Rico. I want to leave today and come back in 4 days. I would like to leave and come back in the morning.
Okay, do you have any other preferences?
Okay.
If you want to leave today from New York to Puerto Rico and  come back and 4 days is that correct.
Yes, that's correct.
Okay, perfect.
I would like to have the least total travel time.
Alright, great. It looks like you can leave today at 8:25 PM. It will be the cheapest price for $437 and it is a non-stop flight.
Cool, what about my return? Can you give me a morning flight?
Okay.
No. I meant my return flight. I want to depart in the morning.
Please, wait for a while. For your return flight you could leave at 6 AM.
Sounds pretty good. I'll take that.
That is the earliest flight.
All right, book that for me.
You are all set.
All right. Thank you.
You're welcome. Bye.
