Query: user: I need to go visit my family on short notice. Can you find a round trip flight for me that leaves on the 3rd and returns Thursday next week?
assistant: Sure, where are you going?
user: I'm going from New York to Atlanta, GA.
assistant: Ok, I found 4 flights that look pretty good. There's an American Airlines flight for $134 that departs at 11:20 am on the way there, and 6:25 am on the way back. How about that one?
user: That sounds good. Can you buy me a ticket?
assistant: Sure. To confirm, you want 1 Economy ticket on American Airlines from New York to Atlanta that departs at 11:20 am on March 3rd and returns at 6:25 am on March 7th. Is that right?
user: No, can you upgrade that to Premium Economy?
assistant: No problem. To confirm, you want to book one ticket in Premium Economy to Atlanta, is that right?
user: Yes, that's perfect.
assistant: Ok, I've booked your ticket.
user: Great, which airport does it fly out from?
assistant: It departs from JFK International Airport.
user: Ok, and when does it arrive at the destination? Also, is it refundable?
