Aviation History
Danish aviation dates to 1906, when inventor Jacob Ellehammer made one of Europe's earliest sustained powered flights near Lindholm, giving Denmark an early place in aviation history. Commercial aviation followed with the founding of Det Danske Luftfartselskab (DDL, Danish Air Lines) in 1918 and the opening of Kastrup Airport near Copenhagen in 1925, one of the world's oldest continuously operating airports. In 1946 Denmark joined Norway and Sweden to found the Scandinavian Airlines System (SAS) consortium, which fully merged in 1951 and went on to pioneer transpolar routes in the 1950s. SAS remained Denmark's dominant carrier through the postwar decades, competing at times with independents such as Maersk Air, and in the 2020s underwent a Chapter 11 restructuring that shifted its ownership and alliance membership. Copenhagen Airport today remains Scandinavia's largest aviation hub.
Inventor Jacob Ellehammer flew his semi-biplane near Lindholm, one of the first sustained powered flights in Europe.
Det Danske Luftfartselskab was established as Denmark's first airline, later a founding partner of SAS.
Copenhagen Airport at Kastrup opened, becoming one of the world's oldest continuously operating airports and Scandinavia's main gateway.
Denmark, Norway and Sweden formed the Scandinavian Airlines System consortium, fully merging operations in 1951.
SAS became the first airline to fly a scheduled transpolar route, linking Copenhagen to Los Angeles via Greenland and Canada.
The Maersk shipping group launched Maersk Air, which became Denmark's leading independent airline until its operations were absorbed into SAS in the mid-2000s.
Financial deterioration led SAS to file for Chapter 11 protection in the United States in July 2022 to restructure its debt and ownership.
A new investor consortium including Air France-KLM took a stake in SAS, which exited Star Alliance and joined SkyTeam in 2024.

Compiled from general public/encyclopedic sources (Wikipedia, SAS Group corporate history); SAS's ownership and alliance status changed as recently as 2024 and could shift further.

Copenhagen Airport (Kastrup) — Copenhagen (1925): Inaugurated 20 April 1925; described as 'one of the first civil airports in the world' and 'one of the oldest international airports in Europe' — the source deliberately avoids claiming it is 'the' oldest, and operations were interrupted during WWII (limited to flights to Sweden/Nazi Germany), so continuity was broken. · CPH ↗ · Wikipedia ↗
Danish Air Lines (DDL / Det Danske Luftfartselskab) (1918): Established 29 October 1918; first scheduled route 7 August 1920. On 1 October 1950/51 (sources disagree on the exact year), DDL and two other Scandinavian airlines agreed to have the newly formed SAS run airline operations; DDL continued only as a holding company for Danish SAS interests. No older Danish rival airline was found. · Wikipedia ↗
Swissport (Switzerland), 2012: Swissport launched cargo-handling operations at Copenhagen Airport on 1 July 2012, explicitly described by trade press as 'Swissport's first cargo station in the Nordics' — the strongest 'first' language found for any of the 20 pilot countries. Caveat: this is specifically cargo-handling, not confirmed as the first full (ramp/passenger) ground-handling entry into Denmark, which was historically dominated by domestic SAS Ground Handling. (best-documented candidate found — not source-confirmed as literally first.) · JOC ↗
