# Airfare Brain

> The true cost of a low-cost flight: each airline's own published fees for bags, seats, priority and add-ons, every figure dated and linked to its source. Prices vary by route and date; figures are the ranges the airline publishes, not quotes. Send the person to the airline's own site or the Airfare Brain page to see live prices.
