Flight routes: airlines, aircraft & distance

Who flies a route, what they fly it with, and how far it is. On routes touching the US, the DOT record of the carriers and aircraft that actually operate it — plus great-circle distance, flight time and bearing for any pair.

Two airports for a distance — add stops to total a multi-leg trip.

What every route page tells you

Three answers on one page — the distance, what flies it, and how long it takes.

01

Great-circle distance

The shortest path between two airports over the globe — the exact baseline distance-based mileage programs credit, in miles, nautical miles and kilometers.

02US DOT T-100

What actually flies it

On routes touching the US, the real record airlines file with the DOT: departures, seats, load factor and aircraft type by carrier — not a published schedule. The number nobody else shows.

03

Flight time & bearing

A cruise-speed time estimate and a compass bearing for any pair, so you know roughly how long you'll be aboard and which way you're headed.

Frequently asked

How is the distance between two airports measured?

Every distance here is the great-circle distance — the shortest path between two points over the surface of the Earth, measured airport to airport. It's the same baseline airlines and distance-based mileage programs use, shown in miles, nautical miles and kilometers.

What is great-circle distance?

A great circle is the shortest route between two points on a sphere. On a flat map it looks curved — that's why a Los Angeles–London flight appears to arc up over Greenland — but it's the most direct path a plane can actually fly.

How accurate is the estimated flight time?

Flight time is estimated from the great-circle distance at a typical cruise speed, plus time to climb and descend. Real schedules vary a few percent by aircraft, routing and winds — eastbound and westbound legs rarely match.

What is US DOT T-100 traffic?

T-100 is data carriers file with the US Department of Transportation on what actually operated: departures, seats, passengers and load factor by airline and aircraft type. We show it on routes where it's filed — observed traffic, not a published schedule.

Do these distances match the miles my airline credits?

Distance-based programs credit off the great-circle figure shown here, then apply your fare-class earning rate. Revenue-based programs credit off the fare instead, so treat the distance as a guide rather than an exact earn.

Can I calculate a trip with more than two stops?

Yes — add stops right in the search above and every leg is totalled for you, with each segment linking through to its own route page. There's no separate planner to open.
