User requests (one per turn):
user: Hey, I'm in the mood for a last-minute getaway! I need some help figuring out how much it's going to cost for a first-class flight between the first two airports on your destination list. Planning to leave next Friday 19th Sept 2024 and want to make sure I can travel in style.
user: So, I've been thinking about how much I want to spend on my travels. I'd like to set a budget cap. Can you, with my authorized access, set a limit of $10,000 for any travel expenses I might incur? 
user: access token is abc123xyz
user: I'm feeling a bit uneasy and decided it might be a good idea to get some travel insurance. Could you arrange this for my latest reservation (with id 'latest_reservation'), making sure it stays within my budget? Please use my credit card with ID 'primary' and access token 'abc123xyz'. I am willing to pay the $500 premium.
user: The purchase is finally done, and I’d appreciate it if you could help me look over the invoice details for my booking. I just want to double-check to ensure everything’s correct.
user: I can't wait to explore this new destination! I'm really excited to share my travel itinerary on Twitter. Could you post a tweet 'Excited for my upcoming adventure!' about the upcoming adventure for me? Make it interesting with the hashtag '#TravelGoals' and don't forget to mention '@TravelBuddy' to invite them along!
user: Oh, I just noticed an amazing tweet from @TravelInsider about dream destinations. It’s exactly what I’ve been dreaming about, and I'd love to share it with my followers. Would you mind retweeting tweet id 0?
