It is the largest airport in the western hemisphere by land area, roughly twice the size of Manhattan, and the runways are that far apart because at 1,655 m of elevation aircraft need more of them. The automated baggage system it opened with failed so comprehensively that it delayed the whole airport by sixteen months and was abandoned entirely in 2005.
Codes it used to have
| Code | Until | What happened |

| DEN | — | The code moved with the city, from Stapleton International to the new field 25 miles further out in 1995. |
The other code, KDEN
Every airport has two codes. The three-letter IATA code, DEN, is the one on your boarding pass and your luggage tag, and it is assigned for commercial use. The four-letter ICAO code, KDEN, is the one pilots and controllers use, and it is assigned geographically: the first letter or two identify the region, so every airport in the same part of the world shares a prefix. That is why KDEN looks nothing like DEN.
