Before you call either
LetsFG
- Start on
/v1/sandbox/with no key; the booking states, questions and timings match production - After
book_flight, pollget_flight_bookingevery 20 to 30 seconds and answer questions beforeexpires_at_ms; an unanswered price change fails the booking and releases the hold - Honour
retry_after_secondson a 429. Over MCP the limit is 10 searches per 10 minutes and 100 a day, and early retries lengthen the pause - Fetch results with
get_flight_resultsand thesearch_idrather than searching again, which spends allowance - Send the same
idempotency_keywhen retrying a booking after a timeout - Treat a 410 as a retired route and read the replacement path in its body
Lola
- Have the traveller confirm booking details, charges and cancellation terms.
- Check whether a membership benefit is live before relying on it.
