When does this flight take off?
I want to go sightseeing in Beijing next week. Can you recommend a flight from Shenzhen to Beijing for next Friday? Economy class will do.
user
Sure, just a second. I recommend you to take CZ3171 of China Southern Airlines from Terminal 3 of Bao'an International Airport to Terminal 2 of Beijing Capital International Airport.
assistant
It'll be my first trip to the capital, I don't know a single person there. I care a lot about the arrival time. Can you help me check it?
user
I see. The arrival time is 00:05 the next day. You'd better book a hotel room in advance.
assistant
So it arrives in Beijing at midnight, that's quite late. Is this flight normally on time?
user
The punctuality rate is quite low, only 89.44%.
assistant
Sounds risky. I'll make it my plan B. How much is a ticket for this flight?
user
I'd say the ticket is quite affordable, only 770 yuan.
assistant
That's quite cheap indeed. Can you tell me the departure time?
user
Sure, the departure time is not that early either, it takes off at 20:40 that day.
assistant
I think I'll look at some other flights. Do you have a flight from Shenzhen to Beijing next Tuesday? If you do, please tell me the flight information.
user
There is one, the same flight I just told you about. CZ3171 of China Southern Airlines from Terminal 3 of Bao'an International Airport to Terminal 2 of Beijing Capital International Airport.
