Conversation

Search flights from SFO to JFK. Before you try to book anything, examine the validity_window field in the results. Tell me: how long are these offers valid? What happens if they expire? Should you hold them first?
I'll search for flights from SFO to JFK and then examine the validity windows for you.
Perfect! Here's what I found regarding the validity windows:

Flight Options Found:
1. United Airlines UA 2847 - $388.41 (nonstop, 5h 27m, departs 8:15 AM)
2. Delta Air Lines DL 1053 - $432.10 (nonstop, 5h 35m, departs 11:30 AM)
3. American Airlines AA 178 - $305.82 (1 stop in DFW, 5h 50m, departs 2:20 PM)

Validity Window Analysis:

How long are these offers valid?
- Only 30 seconds! Each offer has a `ttl_seconds` of 30, expiring at 2026-04-06T13:08:00+00:00.

What happens if they expire?
- The notice is clear: "This fare offer expires in 30 seconds. After expiry, you must re-search to get a current price."
- If you try to book an expired offer, you'll get an `OFFER_EXPIRED` error
- You must search again to get fresh, current pricing

Should you hold them first?
- Yes, absolutely! If you need time to decide or gather passenger details, you should use the `hold_offer` function
- Holding an offer extends its validity window by 5 minutes, giving you breathing room
- This is crucial for these ultra-short 30-second windows

This is typical for airline fare pricing—seats and prices fluctuate rapidly. Would you like me to hold one of these offers so we have more time to discuss booking, or would you prefer to search for different dates/parameters?
