Yeah, I'd like to book a flight from Los Angeles to Houston.
You got it. When would you like to depart?
I'd like to depart as late as possible on both legs and I would like to leave tonight and returning in 2 days.
Any other preferences?
Yeah, I would like it to be the cheapest and first-class.
The cheapest first-class flight costs $753, leaving at 11:30 PM with one-stop.
That sounds good.
Would you like to book a return flight with the same preferences?
Yes.
The latest non-stop flight costs $914 and leaving at 1:05 PM.
That's fine.
Okay, you're all booked.
Thank you.
Have a safe flight.
