Flights to Thornton
Which airport to land at, how far each is from the centre, and where the routes go. Live fares are booked here.
Thornton is served by 2 airports with scheduled flights within 100 km. The closest large one is Denver International Airport (DEN), 25 km (16 mi) from the centre, whose 16,000-ft runway is long enough for long-haul wide-body aircraft. The alternatives are Rocky Mountain Metropolitan Airport (BJC, 13 km).
| Airport | Code | From centre | Longest runway | Elevation |
|---|---|---|---|---|
| Denver International Airport | DEN | 25 km (16 mi) | 16,000 ft | 5,431 ft |
| Rocky Mountain Metropolitan Airport (regional) | BJC | 13 km (8 mi) | 9,000 ft | 5,673 ft |
Runway length is a practical tell: at 16,000 ft, DEN can take the largest long-haul aircraft, so direct intercontinental flights are physically possible here. The airport sits at 5,431 ft; that altitude thins the air enough to affect take-off performance on hot days, which is why summer departures from high airports are sometimes weight-restricted.
