Hi, I would like to book a round trip commercial airline flight from Los Angeles to Boston.
Ok, can you give me some specifications?
Yes, I would like to be today for the departure, and return in four days from now?
What seating class do you prefer?
The cheapest economy class.
Did you want to leave in the morning or afternoon flight?
Earliest possible in the morning.
Do you prefer non-stop or layover?
Non-stop.
Ok, one moment, hold. I found a flight for you is United Airlines that departs at 10:47 p.m and arrives at 7:14 a.m.
Okay, perfect.
The total price is $555. You are all set.
