Metro Airlines
Metro Airlines, originally Houston Metro Airlines, was a commuter airline that was originally headquartered in Houston, Texas, United States. Metro subsequently moved its headquarters to north Texas. The airline had an operational base located on the grounds of Dallas/Fort Worth International Airport and also had offices on the airport property and in Grapevine, Texas. Metro evolved into an airline holding company with the acquisition or creation of a number of different airlines, including as the banner carrier (commercial aviation) operating feeder services for Eastern Airlines as Eastern Metro Express which was based in Atlanta, GA and Metroflight  which operated American Eagle service from the Dallas/Ft. Worth Airport. The company filed for bankruptcy in 1993, and the assets were acquired by AMR Simmons Airlines. History. In 1969 the airline was founded to serve the Houston area with "cross-town" flights. Houston Metro Airlines constructed their own 2,500 foot, short take-off and landing (STOL) airstrip along with a passenger terminal building and maintenance hangar adjacent to Clear Lake City, Texas near the NASA Johnson Space Center. The Clear Lake City STOLport was essentially Houston Metro's own private airport. The airline's initial route linked Clear Lake  City (CLC) with Houston Intercontinental Airport (IAH) which opened in 1969. In early 1970, Houston Metro was operating two routes: Clear Lake City - Houston Intercontinental and Houston Hobby Airport (HOU) - Houston Intercontinental. The February 1, 1970 Houston Metro timetable lists 24 round trip flights every weekday between the CLC STOLport and Houston Intercontinental and 14 round trip flights every weekday between Houston Hobby and Houston Intercontinental. According to the February 1976 edition of the Official Airline Guide (OAG), the airline was operating 22 roundtrip flights every weekday in its passenger shuttle operation between Clear Lake City and Houston Intercontinental. The  route system was later expanded to include a number of destinations in southeast and south Texas with flights to George Bush Intercontinental Airport. At one point, the airline also flew between Laredo, TX (LRD) and San Antonio, TX (SAT). All initial Houston Metro service was operated with de Havilland Canada DHC-6 Twin Otter twin turboprop STOL aircraft as the Clear Lake City STOLport was specifically designed for this aircraft. Additional new service was later extended to Lafayette, LA (LFT) and Lake Charles, LA (LCH) with flights to Houston Intercontinental (IAH) with these services being operated with larger Short 330 twin  turboprop aircraft. The Short 330 was also utilized by Metro for flights between IAH and Beaumont/Port Arthur (BPT) where one was destroyed by a tornado in 1983 while sitting empty on the airport ramp (see Accidents and incidents below). In 1972 the airline carried between 90,000 and 100,000 passengers per year. It displayed a profit of $156,510 U.S. dollars in an eight-month period. In 1978 Metro entered the "stand up widebody cabin age" when the first orders for five (5) Short 330 twin turboprops were announced. These Irish-manufactured aircraft would be used to complement the Twin  Otters already in use on higher demand routes as well as new service to Lafayette, LA and Lake Charles, LA and offered far more comfortable seating for passengers. The addition of the 30 passenger Short 330 turboprops required Metro to make provisions for flight attendants and also resulted in the carrier joining the ranks of the regional airline industry via its use of larger aircraft. The company was also independently operating flights from the Dallas/Fort Worth Airport (DFW) at this time with DHC-6 Twin Otter and Short 330 aircraft with services to several destinations in east Texas with some  of these flights continuing on to or originating from Houston Intercontinental (IAH). These Twin Otter and Short 330 passenger services into DFW were flown by the Metroflight Airlines division which would eventually operate American Eagle flights. Metroflight also independently served several destinations in Oklahoma and north Texas from Dallas/Ft. Worth and Oklahoma City (OKC). In 1982 Metro purchased fourteen (14) Convair 580 aircraft from the original Frontier Airlines. These 50 passenger twin turboprops were then used to initiate the first ever American Eagle service via a new code sharing passenger feed agreement with American Airlines. The Convair 580 aircraft  were operated by the Metroflight Airlines division which also flew DHC-6 Twin Otter aircraft on American Eagle services. Metro Airlines operated out of Dallas/Fort Worth International Airport via its wholly owned Metroflight division under the American Eagle brand beginning on November 1, 1984. In 1985 the airline announced that it would end service to Houston Intercontinental Airport (now George Bush Intercontinental Airport). Royale Airlines, a commuter/regional air carrier based in Louisiana, then assumed many of the routes that were previously operated by Metro into Houston. However, in 1987 Royale declared bankruptcy and ceased all scheduled passenger flight operations . Acquisitions and subsidiaries. Metro Airlines spun off its certificated airline, being Metro Airlines, and formed an airline holding company. Among the commuter and regional air carriers acquired or created by Metro were: Bankruptcy. In 1991 Metro went into Chapter 11 bankruptcy reorganization and then in May 1993 Metro Airlines went completely out of business. The airline assets were promptly purchased and renamed by AMR Corporation whom were already involved with Metro Airlines by way of the "banner carrier" codeshare flying that Metro performed for AMR via its Metroflight division with these services being created cooperatively by the legacy carrier, being  American Airlines, and the regional, being Metro subsidiary Metroflight, as American Eagle during the mid-1980s. Under AMR many of Metroflight's assets found their way over to Simmons Airlines. Houston Metro's original home, being the Clear Lake City STOLport located in the Houston area near the NASA Johnson Space Center, was abandoned and subsequently demolished in order to make way for suburban development. There is currently no trace of this pioneering airfield to be seen. In later years, Continental Express, a regional airline and a regional airline brand; and at that time survivor of the post-deregulation and highly  controversial Houston based Texas Air Corporation Continental Airlines and Eastern Air Lines acquisition years, operated scheduled passenger air service from Ellington Field (EFD) near the former site of the Clear Lake City STOLport. Much like the original Houston Metro, and subsequent Eastern Metro Express short hop operations by amicable partner Metro Airlines; short hop Continental Express flights commenced during the 1980s, utilizing ATR-42 and Embraer EMB-120 Brasilia turboprops and then Embraer ERJ-135 regional jets to transport connecting passengers across the city to Houston George Bush Intercontinental Airport (IAH). However, this service was finally discontinued as well. These destinations were served  by Houston Metro Airlines during and after its name change to Metro Airlines from its Clear Lake, City headquarters, with de Havilland Canada DHC-6 Twin Otter turboprops and/or with Short 330 turboprops: These destinations were initially served independently by the Metroflight division with de Havilland Canada DHC-6 Twin Otter aircraft: Metroflight would later operate codeshare services for American Airlines flying Convair 580 turboprops as American Eagle. Destinations on behalf of American, Eastern and Trans World Airlines. These destinations were served with British Aerospace BAe Jetstream 31 turboprops and/or with de Havilland Canada DHC-8-100 Dash 8 turboprops: After the acquisition  of the airlines "Sunaire" and the subsequent name change to "Aviation Associates," de Havilland Canada DHC-6 Twin Otter 250 & 300 turboprops served the following destinations: Many of these destinations were served previously to Metro Airlines marketing alliance with Eastern Airlines and formerly utilizing the original carriers very own DHC-6 Twin Otter aircraft: Metro was also operating Eastern Express service at this time from San Antonio International Airport (SAT) with service to Laredo, TX (LRD) After the acquisition of the airline "Brockway Air" and its subsequent name change to "Metro Air Northeast," Beech-1900C and Saab-340A commuter aircraft served the following destinations  upon TWA's TWExpress network:
