Flying FineWhat does business class cost from SFO to JFK?Flying FineI have $1200 — where can I fly business from JFK?Flying FineI'm looking at a $300 economy flight to Miami. What would business be?

You were going to spend $300 on a seat at the back. On that route, on that date, the flat bed might be closer than you think — or far further away. Flying Fine tells you which. Ask what business or first class costs on any of 1,503 US domestic routes and you get the real range: the cheapest fare recorded, the typical fare, and the high end — drawn from actual tickets sold, published quarterly by the US Department of Transportation. Give it a budget instead and it will show you which routes that money can actually reach, longest trip first. It also separates lie-flat beds from reclining seats. On some routes the cheapest premium ticket is a recliner while a genuine flat bed costs a few hundred more, and price alone will not tell you which is which. These are historical figures, not live fares, and the plugin says so every time. Where a route rests on only a few dozen recorded tickets it flags that too, rather than presenting a thin number as a firm one. There is no booking and no checkout — you confirm with the airline.
