On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 200 ms.

• Its tools do every use case we checked: Submit bids for upgrade eligibility on a booking; Complete instant upgrades programmatically through the agent API; Automate upgrade actions without operating the web page.
• Checked on 3 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• check_upgrade_eligibility

  Looks up a booking's upgrade eligibility from a booking reference and last name, and airline. Returns eligibility status, upgrade options, bid ranges, and a session id for follow-up bid tools.

• start_eligibility_check

  Starts an upgrade eligibility check for a flight, cruise, or rail booking. Returns a secure page (and, where supported, an inline form) for the traveler to enter their booking reference and last name.

• mint_eligibility_session

  Internal helper for the inline eligibility form: creates a secure session and returns its id. No UI; agents should use start_eligibility_check instead.

• get_eligibility_result

  Read the result of a secure eligibility check started with start_eligibility_check. Pass the sessionId returned by that tool. Returns the live eligibility outcome (eligible options, bid ranges, offer URL) once the passenger has submitted…

• cancel_bid
