Overview
Quantum Air was a Spanish passenger airline based in Madrid and the successor to AeBal, whose original full name was Aerolíneas de Baleares. The business was established in 1999 and initially had its headquarters at Son Sant Joan Airport in Palma de Mallorca. It was created to operate aircraft and services connected with Spanair and was originally intended to use the name AB Bluestar, although that name was changed before operations began. The airline commenced flying on 5 July 2000 from Madrid with three Boeing 717 aircraft. During its early period it operated under the AeBal - Spanair Link identity, retaining a close commercial and visual association with Spanair. Its activities included domestic scheduled passenger services in Spain, charter flying and ACMI or wet-lease operations elsewhere in Europe. The original ownership structure comprised Grupo Marsans with 51 percent, SAS Group with 25 percent, Spanair with 18 percent and VITRAC with 6 percent. Subsequent changes in the shareholding structure resulted in SAS Group becoming the sole owner. The company employed 155 people in March 2007. AeBal's principal operating model initially depended heavily on wet-leasing aircraft to Spanair for domestic and international routes. That arrangement ended during Spanair's restructuring: AeBal ceased operations on 16 September 2008 after its wet-lease agreement was cancelled. The company was subsequently sold by SAS in January 2009 to Proturin, a Spanish investment company controlled by Antonio Mata, who had previously been chief executive of Aerolíneas Argentinas. In March 2009, the business re-emerged under the Quantum Air name and moved its principal base from Mallorca to Madrid-Barajas Airport. Under the Quantum Air brand, the airline sought to operate its own scheduled network rather than relying solely on the former Spanair wet-lease relationship. Its published domestic network included Madrid, Palma de Mallorca, Bilbao, Fuerteventura, Gran Canaria, Lanzarote, Tenerife North, Málaga, Seville, Alicante and Santiago de Compostela. The airline also retained the ability to undertake charter and ACMI work across Europe. The fleet was associated with Boeing 717 aircraft and older McDonnell Douglas MD-87 aircraft. An attempt to replace the ageing MD-87 fleet with newer Boeing 717 aircraft was not successful. The rebranded airline experienced severe financial and operational difficulties. Defaults on aircraft lease payments led SAS to seek repossession of the aircraft, and the resulting legal dispute contributed to the grounding of the fleet. Quantum Air temporarily stopped operations and ticket sales on 26 January 2010. The airline did not return to sustained commercial service and is regarded as defunct. In October 2012, a court in Palma de Mallorca ruled in favour of the company in litigation involving SAS and ordered SAS to pay €6.3 million. The aircraft associated with the airline were later delivered to Blue1, with deliveries reported as beginning in September 2010.
History
Quantum Air originated as AeBal, short for Aerolíneas de Baleares, a Spanish airline established in 1999. The company was initially planned under the name AB Bluestar and was headquartered at Son Sant Joan Airport in Palma de Mallorca. It began operations on 5 July 2000 from Madrid with three Boeing 717 aircraft. Its early commercial identity was AeBal - Spanair Link, reflecting its relationship with Spanair and its role in providing aircraft and capacity for Spanair services. The initial ownership structure included Grupo Marsans, SAS Group, Spanair and VITRAC. Grupo Marsans held the largest initial share, while SAS and Spanair supplied important strategic and operational links. Later changes resulted in SAS Group owning the company outright. AeBal operated scheduled domestic services as well as charter and ACMI or wet-lease flying around Europe. By March 2007, it had 155 employees. A major change came in 2008. AeBal's aircraft had originally been wet-leased to Spanair for domestic and international flying, but the relationship ended as part of Spanair's economic restructuring. AeBal ceased operations on 16 September 2008 after the wet-lease agreement was cancelled. SAS subsequently sold the company in January 2009 to Proturin, a Spanish investment company controlled by Antonio Mata, a former chief executive of Aerolíneas Argentinas. In March 2009, the airline adopted the Quantum Air name and transferred its principal base from Mallorca to Madrid-Barajas Airport. It attempted to develop a direct scheduled passenger operation in Spain. The network listed in July 2009 included Madrid, Palma de Mallorca, Bilbao, Fuerteventura, Gran Canaria, Lanzarote, Tenerife North, Málaga, Seville, Alicante and Santiago de Compostela. Alongside scheduled flying, Quantum Air continued to be associated with charter and ACMI activities. The business faced difficulties with its aircraft leases and fleet planning. An attempt to replace the ageing MD-87 aircraft with newer Boeing 717 aircraft did not succeed. After several lease-payment defaults, SAS sought to impound the fleet. The aircraft were grounded while the parties pursued legal remedies, undermining Quantum Air's ability to operate. The airline stopped operations and ticket sales on 26 January 2010 and did not return to sustained service. The fleet was later delivered to Blue1, with deliveries reported as starting in September 2010. In October 2012, a Palma de Mallorca court ruled in favour of Quantum Air in its dispute with SAS and ordered SAS to pay €6.3 million. Despite that judgment, Quantum Air remained defunct.
