Hi. I would like your help in finding a round-trip commercial airline flight. I'm traveling from New York City to Berlin, Germany. And I would like to depart on Sunday and return 5 days later. I want the departure, return time of the day to be as earliest as possible. Can you help me find a flight, please?
Would you like to travel by economy or business-class?
Economy class. I would like it to be the cheapest as possible, please.
The cheapest flight that I have found is for $932 but it is a one stop flight.
Can you make it a round-trip flight, please?
That is a round trip with one stop.
Okay, I'll take that.
Would you like me to provide the details to you?
Yes, please.
This flight will depart New York at 1 AM  has a layover in Moscow arriving Berlin at 9:30 PM. Will this work for you?
Yes.
Would you like me to provide the return flight details to you?
Yes, please provide them to me.
I have found a flight that departs Berlin at 10:50 PM has a layover in Moscow and arriving NYC at 11 PM.
Sounds great.
Do you want me to go ahead and book the tickets for you?
Book the tickets, please.
The tickets have been booked and the details have been emailed to you.
Thank you so much.
Your welcome. Goodbye.
