I need a flight from San Francisco to London.
When will you be traveling?
I need to leave this Sunday and I need to come back 5 days after that. Can you find a flight that leaves as early as possible on Sunday?
Would you prefer a non-stop or a one stop flight?
Just as long as it's round-trip.
And would you like to travel by economy or business-class?
I don't know. Could you just get me a list of flights?
Through economy, I have found in Lone Star flight departing San Francisco at 4:05 p.m. arriving London at 10:35 a.m.
Well, I'd like the flight to be non-stop if that's possible. And is 4:05 like the earliest you could find for a flight?
Yes, that's the earliest non-stop flight available.
Alright. Cool. Does that have Wi-Fi, too?
No, that does not have Wi-Fi.
Alright. And can you find a return flight for me?
Okay, the one with the Wi-Fi departs at 5:45 p.m. from San Francisco and arrives London at 12 pm.
Okay. And how about the one from London to San Francisco?
From London, I have found a non-stop flight departing at 12 p.m. and arrive in San Francisco at 3:05 pm.
Alright. Sounds good.
This has Wi-Fi. Would you like me to book it for you?
Yes, please.
The booking has been done and the details have been emailed to you.
Alright. Thank you.
You're welcome. Bye. Until next time.
