2005, bringing Comair into bankruptcy along with it. Comair announced that would cut costs by million dollars annually. These savings were achieved by aircraft, flight, and employee reductions. In late 2006, Comair opened an additional crew base and hub at New York City's JFK Airport. Comair had the lowest percentage of on-time flights of all major U.S. carriers during late 2006. This was the result of starting operations at JFK, a congested airport with poor staffing and an unfortunate terminal and aircraft ramp layout that severely dropped Comair's ratings in the DOT listings. In 2008, Comair tied with American for the lowest on-time performance, with 70% of its flights arriving on-time. During the course of 2007, Comair closed down its crew bases in Greensboro, North Carolina and Orlando, Florida. On May 25, 2007, Delta announced that Comair would operate 14 stretched CRJ900 aircraft for Delta Connection. These aircraft were to replace 14 smaller CRJ100 aircraft in Comair's fleet. Parent company Delta Air Lines replaced Comair's service in these destinations with Atlantic Southeast Airlines, a subsidiary of SkyWest, Inc., and Chautauqua Airlines, a subsidiary of Republic Airways Holdings. In early 2008, Delta announced it was going to reduce its domestic capacity by 4-5%, in which Comair would reduce its 50-seat Canadair Regional Jet fleet by 8-14 aircraft. In March 2008, when the price of oil rose, Delta announced it would further reduce domestic capacity. On February 10, 2009, Delta Connection announced that ground handling and gate service positions for Comair, Mesaba Airlines, and Compass Airlines would be transitioned to a new Delta Air Lines subsidiary. The interim name of the new company was Regional Handling Services until a new name was confirmed before September. Each airline maintained its own flying operations. Services including ticketing and baggage handling were to be handled by RHS beginning in the 3rd Quarter of 2009. There was to be a reduction in the workforce. The largest cut was to come from Comair which was to reduce its staffing by nearly half. A voluntary termination was introduced and involuntary cuts were possible later in the year as Delta mainline ground employees took over positions of Delta subsidiary ground employees that had been contracted to Comair and then Regional Elite Airline Services. On September 1, 2010 Comair announced that it would reduce its fleet by eliminating all of its aging Bombardier CRJ100/200 aircraft, expecting to have retired them
