Use for 'flying to Faro with Ryanair, bags and a hire car: what will it cost?'.

`true_cost`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.	The true cost of a flight on one airline.
