Multi-turn user requests:
user: I'm planning to jet off and stumbled upon a nifty flight from San Francisco to Los Angeles. Lowkey, my budget isn't too tight, but just make sure overall cost for the flight is below $10,000? You should know my travel class is 'first' and travel date is '2024-11-15'. Oh, and I've got my card with id 'card123' and account token 'access_token_abc123' all good to go.
user: With my flight all set, can you whip up those invoice details for me? I need a nice little record of when I'm traveling, where I'm headed, and how much it's setting me back.
user: If things go south with my itinerary, could you be a champ and get me in touch with customer support? Just mention my confirmed booking when you connect us.
user: Thinking I might need to call off this trip. Could you chat with support to cancel my reservation and make sure my account gets the refund? Thanks a bunch!
user: I've picked up some nifty travel insights from my adventures, and I've got the itch to share them. Could you pen a tweet on my behalf using username 'michael_smith' and password 'michael1234' if I toss you the points? The tweet should say 'Exploring the world, one city at a time!'. Maybe sprinkle in trendy hashtags 'Travel' and 'Adventure'.
user: Wow, the tweet with the travel tips got a hit! Can you give it a boost by retweeting it for me? Let's get it out to even more folks.
