Mesa Air Group, Inc. is a Nevada Corporation commercial aviation holding company with headquarters in Suite 700 at 410 North 44th Street in the Camelback East area of Phoenix, Arizona, United States. The company operates one regional airline subsidiary: Mesa Airlines which operates as American Eagle, US Airways Express and United Express under contractual agreements with American Airlines and United Airlines respectively. As of April 2015, Mesa operates 97 aircraft with approximately 420 daily system departures to 94 cities, 38 states, the District of Columbia and Mexico. The company, founded in Farmington, NM in 1980 and purchased by Larry and Janie Risley in 1982, has approximately 2,500 employees. In terms of revenue, Mesa Air Group at one point would be considered a major airline carrier as it has over $1 billion annual revenue earnings, however it does not qualify for major status because its aircraft seat fewer than 100 people. At its peak during September 2007, Mesa Air Group operated 201 aircraft. On January 5, 2010, Mesa Air Group filed for bankruptcy. The company emerged from bankruptcy on March 1, 2011. Mesa began in 1980 when JB Aviation, a fixed-base operator at the Four Corners Regional Airport in Farmington, New Mexico, established a charter flight department and Mesa Air Shuttle with scheduled commuter airline service from Farmington to Albuquerque, NM using a five-seat single engine Piper Saratoga aircraft. A nine-seat Piper Navajo was later added for new service from Farmington to Denver. In late 1981 the Denver flights were discontinued and a new route from Farmington to Grand Junction, CO and Vernal, UT was briefly added. In 1982, using $140,000 in capital, Larry Risley, an A&P mechanic with JB Aviation, and his wife Janie, purchased the airline and by mid 1983, acquired its first 14-seat Beechcraft 99 airliner. New service from Albuquerque to Durango, CO began with the arrival of the second Beech 99 later that year. More Beech 99s were acquired and the company continued to expand from Albuquerque to other cities throughout New Mexico as well as Lubbock, TX.
