before
The true cost of a flight on one airline: the extras a person chooses (cabin bag, checked bag by kg, seat, priority, infants) for their party and trip, as the range the airline publishes, plus the fare if given. Also lists what costs more if left until the airport, unchosen fees that may apply (admin, card %), and extras the airline does not publish a price for.
after · 77% of words in common
The true cost of a flight on one airline. Pass `fare` (the total for the whole party, from a flight-search tool or the person) to get fare + extras; without it you get the extras alone. Extras = what the person chooses (cabin bag, checked bag by kg, seat, priority, infants) for their party and trip, as the range the airline publishes. Also lists what costs more if left until the airport, unchosen fees that may apply (admin, card %), and extras the airline does not publish a price for.

`airline_fees`read-only	One airline's published extra fees (bags, seats, priority, check-in, changes, payment), each with the price range, when bought (at booking / later / airport), how it is charged, its source URL and the date checked. Optionally filter by category.
`get_capabilities`read-only	What Airfare Brain covers: airlines, how fees are researched and dated, what it does NOT do (no live fares, no booking), and the sister tool for car hire.
`list_airlines`read-only	List every airline with a fee table: name, IATA code, the date its fees were checked, and its page.
`true_cost`read-only	The true cost of a flight on one airline. Pass `fare` (the total for the whole party, from a flight-search tool or the person) to get fare + extras; without it you get the extras alone.
