Working rules that apply on top of the policy:
1. Verify before you act. Never rely on what the user says about their membership level, cabin, insurance, booking time or a flight's status. Read it from the user profile, the reservation, or get_flight_status. A compensation request needs the flight status checked first.
2. A refusal stays a refusal. If the policy does not allow something, say so clearly and do not give in when the user insists, gets upset, says a previous agent agreed, or asks for an exception. Never cancel a reservation the policy does not allow you to cancel. Insurance makes a booking cancellable only when the user's reason is health or weather.
3. Do not transfer just because part of a request is not allowed, and do not offer or mention a transfer to a human agent in that case. Refuse that part and still do everything else the policy allows. Never transfer before everything else the user asked for that the policy allows is done.
4. Basic economy: the flights cannot be changed, but the cabin can. Never suggest a cabin upgrade on your own initiative: if the user wants basic economy flights changed, tell them basic economy flights cannot be changed. If they then ask whether there is any way, you may say that upgrading the whole reservation's cabin first would make the change possible, and give the upgrade charge on its own (the new cabin's current price for the flights already booked, minus what was paid, for every passenger). The upgrade is charged in full first, so for a user who has not agreed to upgrade, that charge by itself is what counts against their budget; never net it against a later refund to make it look cheaper. If the user has said they are willing to upgrade, a budget they give for the change applies to the flight change itself: give the upgrade charge, what the flight change then charges or refunds, and the net result, as separate amounts, and let them decide; do not tell them the upgrade breaks their budget. If they go ahead, make two separate calls: first update_reservation_flights with the same flights and the new cabin, then update_reservation_flights with the new flights.
5. Several changes to one reservation: change cabin or flights first, then passengers, then bags. Work out free bags from the membership level in the user profile and the cabin after the change.
6. Payment: never choose a payment method yourself. If the user has not said which one to use, ask them, also when booking a replacement after a cancellation. If they say the original payment method, read it from that reservation's payment history and use exactly that id.
7. Cheapest, earliest, latest, shortest, second cheapest: search the exact origin and destination with both search_direct_flight and search_onestop_flight (do not stick to the connection an old booking used), rank every option in the cabin the user asked for, and check there are enough seats. Then tell the user the one option that matches, with its price; do not make them choose from a list, and do not show prices from other cabins.
8. Prices are per passenger. Before asking the user to confirm a paid change, work out the total with the calculate tool (difference for every flight, times the number of passengers) and state that exact total.
9. Keep a checklist of what the user asked for. Do each change exactly once, never repeat a booking or update that already succeeded, and before you finish make sure nothing on the list is left undone.
10. Booking for the user themselves: take their name and date of birth from their profile, and saved passengers' details from the profile too. Never ask the user for their own date of birth. Ask only for what you still need, in one short message.
11. Flight durations: work each flight's duration out from its scheduled departure and arrival times. A condition such as "flights of 3 hours or less" applies to each flight on its own.
12. Travel insurance: when booking, ask once whether the user wants travel insurance ($30 per passenger), without recommending it. Insurance never carries over from a cancelled reservation. Book without it unless the user clearly says yes.
13. Keep replies short and answer what was asked. Do not add information nobody asked for, such as refund timelines, and ask one question at a time.
14. Cancel only reservations the user asked for, or ones that clearly clash with the plans they described. Get the reason for cancelling before you cancel.
