After the merger, losses mounted[9] and service reductions followed.[10] Saddled with debt from two acquisitions and new aircraft, the airline struggled in the early 1980s,[11][12][13] and even introduced a human mascot version of Herman the Duck.[14][15] They reduced service to Phoenix and Las Vegas, former hubs of Hughes Airwest, citing their inability to compete with non-union airlines there,[16] and eventually dismantled the former extensive route system operated by Hughes Airwest in the western U.S.[17] As a result, this caused the airline’s image to worsen at a sensitive time, and rather than Republic, the airline was becoming known as "Repulsive".[18]
In early 1985 Republic teamed up with Simmons Airlines and Express Airlines I to provide feeder service from dozens of smaller cities to Republic's three main hub airports at Detroit, Memphis, and Minneapolis. The service was known as Republic Express using turboprop aircraft that were painted as Republic Airlines, accommodating from 14 to 34 passengers.[19]
Northwest later merged with Delta Air Lines in October 2008; the deal was finalized in January 2010, with Delta as the surviving air carrier. Republic's hubs in Detroit and the Twin Cities have remained intact with Delta; Memphis was dehubbed in 2013.
Frequent flyer program
In October 1984 Republic introduced a new frequent flyer program called the Perks program. The new program eliminated the need to place a frequent flyer account number sticker on each flight ticket coupon, with earned mileage automatically being assigned to accounts if the reservation was booked directly with Republic. Each flight segment earned a minimum of 1,000 miles or the actual mileage, if greater. A domestic round trip reward ticket was automatically issued every 20,000 miles. The new program included a partnership with Pan American World Airways for earning and redeeming mileage awards. In January 1986, Western Airlines was added as a partner. Effective October 1, 1986, the Republic Perks frequent flyer program was merged into Northwest Airlines which adopted the WorldPerks program name, taken from Republic.
According to the Republic Airlines system route map dated March 2, 1986, the airline was serving the following domestic and international destinations shortly before the merger with Northwest Airlines:[26]
The airline had a high safety rating, but incurred a passenger fatality in 1983 when a section of propeller blade entered the cabin of Flight 927 at Brainerd, Minnesota on Sunday, January 9.[31] Arriving from Minneapolis in sleet and snow showers at 7:40 p.m., the Convair 580 skidded off the right edge of the runway and the right propeller struck a snowbank. Three other passengers were injured, one seriously.[32][33] Following this incident, the airline had a number of close calls in 1983.[13] In 1985, a pilot for the airline named Jack Brasher deviated 700 feet from an assigned altitude in flight. As a result, a warning was issued to him months later. The warning would be named after him - the Brasher warning.[34]
