Air Comet (formerly Air Plus Comet) was an airline based in Madrid, Spain. It operated scheduled long-haul services from Madrid to 13 destinations in Central and South America, as well as services in Europe. Its main base was Terminal 1 at Madrid Barajas Airport. The airline worked together with well-known airlines such as AeroSur in a variety of codeshare agreements.
The airline was established in 23 December 1996 as Air Plus Comet and started operations in 1 March 1997, with base at Madrid Barajas Airport. On 11 December 1996 Oasis airline ceased operations and their only aircraft, an Airbus A310, and a significant part of their staff (pilots, ground and office personnel, etc.) became the foundation of Air Plus Comet. In the initial hurry just after the takeover, and not having decided any commercial name for the airline yet, the ICAO code for the company was filled in simply as MPD, which stands for the last names of their three main directives (Mata, Pascual and Díaz).
It mainly operated long-haul charter services from Madrid and Palma de Mallorca to destinations in America and the Caribbean. It relaunched as a full service carrier under the Air Comet name in January 2007. It was wholly owned by Grupo Marsans.
In January 2007, Air Comet took over some of the now defunct Air Madrid airline's Latin American routes.
Financial troubles and bankruptcy 
On 21 December 2009, a High Court in London emitted a verdict favouring the German bank HSH Nordbank, which had sued Air Comet for not meeting the terms of payment for their leased aircraft. Therefore, the airline became legally unable to either operate their four A330-200's or sell any fare tickets, so Air Comet's directors announced the airline was ceasing operations due to bankruptcy.
Air Comet flew to the following destinations  (as of December 2009):
- North America
- South America
By the time of ceasing operations the Air Comet fleet consisted of the following aircraft (as of 21 December 2009) :
|Airbus A330-200||4||24||0||259||286||One of them ended in Batavia Air|
As of 19 February 2009, the average age of the Air Comet fleet was 12.2 years ().
