Hi, I'd like to book a round trip flight from San Fracisco to Houston.
Okay. What are those dates?
I'll be leaving today and coming back on the 21st and I'd like to take the latest flight possible.
Okay. What seating class do you prefer?
Business and I'd also like the total travel time to be as early as possible.
Okay. I found a flight for you at United Airlines departs at 11:55 PM and arrives at 5:43 AM. Your return flight departs at 9:34 PM and arrives at 11:41 PM.
That would work perfectly. Thank you.
Enjoy your flight.
