Verdicts

LetsFG

Hosted MCP with OAuth 2.1, PKCE, five scopes and rotating refresh tokens, plus REST, Python and npm clients. Tickets are bought by a LetsFG booking agent after the hold, 4 to 11 minutes per the docs, and bookings can pause with questions.

Lola

Free membership and published paid-plan commitments. External agent integration was not verified.

Before you call either

LetsFG

  1. Start on /v1/sandbox/ with no key; the booking states, questions and timings match production
  2. After book_flight, poll get_flight_booking every 20 to 30 seconds and answer questions before expires_at_ms; an unanswered price change fails the booking and releases the hold
  3. Honour retry_after_seconds on a 429. Over MCP the limit is 10 searches per 10 minutes and 100 a day, and early retries lengthen the pause
  4. Fetch results with get_flight_results and the search_id rather than searching again, which spends allowance
  5. Send the same idempotency_key when retrying a booking after a timeout
  6. Treat a 410 as a retired route and read the replacement path in its body

Lola

  1. Have the traveller confirm booking details, charges and cancellation terms.
  2. Check whether a membership benefit is live before relying on it.
