Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.
Where no operator publishes a fare for a corridor, the price here is our own estimate, worked out from the real distance and the real operator through a fare curve that follows lead time, day of the week and season. It tells you roughly what the journey costs. It is not a seat anyone has agreed to sell, and the payment step will not take it.
