Monthly on-time %, average delay and delay causes for one airline, system-wide or at one airport.

Tool description as the model sees it

Monthly on-time performance for one airline, aggregated across all its routes (or just the routes touching one airport), from BTS TranStats Reporting Carrier On-Time Performance. Pass carrier as a 2-letter code (“WN”) or common name (“Southwest”). Pass airport to scope to flights where that airport is the origin or destination. Returns the same per-month shape as route_ontime (flights, on-time %, average arrival delay, cancellations, diversions, delay minutes by cause). months caps how many of the most recently loaded months to return (default 12). Unknown carrier codes are refused with a clear error, never an empty success.

Parameters

`carrier`	string	yes	2-letter carrier code (“WN”) or common name (“Southwest”).
`airport`	string	no	Optional: scope to flights where this airport is the origin or destination.
`months`	number	no	How many of the most recently loaded months to return, most recent first. Default 12.
