I'd like to find a round trek commercial airline flight from Seattle to New York City.
Hi, How can I help you? Sure thing, just to confirm you need the flight form Seattle to New York?
Okay.
When would you like to leave?
I'd like to depart June 6th, 2017. I'd like to return in June 10th.
Okay, what classes you like to fly?
Commercial airline flight and the time of day will be the latest possible for a departure and a return.
I see that latest flight is leaving at 11:15 p.m.
Okay, it could be the cheapest.
The least expensive flight leaves at 5:40 p.m.
Okay.
You are saving $100.
Okay. Alright, thank you.
It has one stop.
