Overview
British Midland International, generally branded as bmi, was a United Kingdom airline whose history extended from a 1938 flying school to a substantial scheduled carrier operating from London Heathrow. Its corporate origins lay in Air Schools Limited, established by Captain Roy Harben to train pilots for the Royal Air Force Volunteer Reserve. After the Second World War, the business developed into Derby Aviation, combining pilot training with charter, freight, aircraft maintenance and brokerage activities. Scheduled passenger services began in the early 1950s, and the company gradually expanded from regional British routes into European flying. The airline adopted the name British Midland Airways in 1964 after acquiring assets associated with Mercury Airlines and moving its base from Burnaston to the newly opened East Midlands Airport. During the 1960s and 1970s, it experimented with jets, inclusive-tour charters, affinity-group flights and international wet-lease operations, but eventually concentrated on scheduled regional and short-haul flying. A significant strategic change came when the company withdrew from uneconomic charter markets and used aircraft such as Boeing 707s for lease operations on behalf of other airlines. This helped it avoid competing directly with larger, vertically integrated tour operators. British Midland became an increasingly important competitor to British Airways during the 1980s. Regulatory decisions allowed it to establish services from Heathrow to Glasgow, Edinburgh and Belfast, placing it directly on the United Kingdom's principal domestic trunk routes. It also secured a Heathrow–Amsterdam service in 1986 and became one of the first independent private airlines to challenge British Airways on an international Heathrow route. The airline differentiated itself through comparatively competitive fares, full onboard service, business-class products and airport lounges rather than through a purely no-frills proposition. Its customer proposition was strengthened by the Diamond Club frequent-flyer programme, the Diamond Service single-class product and later Diamond EuroClass, a dedicated business cabin for European and domestic services. The brand also operated subsidiaries and associated airlines, including Bmibaby, BMI Regional, Loganair and Manx Airlines at different stages. It joined Star Alliance in 2000, giving it a global partnership network and supporting connections through Heathrow. Lufthansa acquired control of bmi and subsequently became its principal owner. The airline retained a large Heathrow presence, at its peak holding approximately 13 percent of the airport's slots and operating more than 2,000 flights per week. Its network covered destinations in Europe, the Middle East, Africa, North America and Central Asia. Nevertheless, the carrier faced structural and commercial pressures, including the cost of maintaining its Heathrow position and the strategic priorities of its parent group. International Airlines Group acquired bmi from Lufthansa on 20 April 2012. IAG did not intend to preserve bmi as an independent long-term brand. BMI Regional was sold separately in May 2012, while Bmibaby ceased operations in September 2012. The mainline bmi operation was progressively folded into British Airways and ceased to exist as a distinct airline brand by 27 October 2012. British Midland International is therefore a defunct airline brand, remembered for its role in opening Heathrow competition, developing premium regional service concepts and building a significant independent British airline before consolidation of the UK aviation market.
History
British Midland International originated in the pre-war aviation training business of Air Schools Limited, founded by Captain Roy Harben in 1938. The organisation operated from an aerodrome near Burnaston, later known as Derby Municipal Airport, and trained pilots for the Royal Air Force Volunteer Reserve. In 1946, its activities were placed within Derby Aviation, which also incorporated Wolverhampton Aviation's charter, freight and maintenance work. Following the post-war transition from training to commercial aviation, Derby Aviation began occasional charter services in 1949 and obtained authority for scheduled services in 1953. Its early routes linked the English Midlands with destinations including Jersey, while international flights to Ostend began in 1956. The airline business was reorganised as Derby Airways in 1959. Domestic scheduled flying, holiday charters and freight work expanded, and the company acquired larger aircraft including Douglas DC-3s and Canadair C-4s. In 1964, after acquiring assets connected with Mercury Airlines, the company adopted the name British Midland Airways and moved its operating base to East Midlands Airport. The new identity used blue and white colours and was associated with the Handley Page Dart Herald turboprop. Minster Assets acquired the airline in 1968. Michael Bishop, who had joined the organisation after working in ground handling, became a key executive and drove its subsequent expansion. British Midland entered the jet era in 1970, but early attempts to compete in inclusive-tour and affinity-group charter markets produced heavy losses. Under Bishop's management, the company withdrew from those activities and concentrated on regional scheduled services, ad hoc charters and wet leasing. Its Boeing 707s were generally leased to other operators rather than used extensively on British Midland's own network. The airline's first major Heathrow route began in 1969, and it later developed services from several London airports. A management buyout in 1978 gave Bishop a leading ownership and governance role. British Midland passed one million annual passengers in 1979. During the early 1980s, regulatory appeals enabled it to launch Heathrow services to Glasgow, Edinburgh and Belfast, bringing it into direct competition with British Airways on important domestic trunk routes. It also became a major operator at Heathrow and established a Heathrow–Amsterdam service in 1986 after changes in UK–Netherlands aviation arrangements. Its service strategy combined competitive fares with full onboard service, lounges and business-oriented products. The airline retired its last Viscount in 1988 and increasingly relied on jet aircraft for core scheduled operations. It introduced Diamond Club in 1987, Diamond Service and later Diamond EuroClass, while also developing interests in regional aviation. Subsidiaries and associated operations included Manx Airlines, Loganair, Bmibaby and BMI Regional. In 2000, bmi joined Star Alliance, reinforcing its international commercial reach. Lufthansa acquired bmi and became its principal owner. At its height, bmi operated more than 2,000 weekly flights and controlled roughly 13 percent of the slots at London Heathrow. Its network extended across Europe, the Middle East, Africa, North America and Central Asia. Lufthansa later agreed to sell the airline to International Airlines Group. The transaction completed on 20 April 2012. IAG sold BMI Regional, closed Bmibaby in September 2012 and integrated the mainline bmi operation into British Airways by 27 October 2012. The British Midland International brand consequently became defunct.
