Elmira Corning Regional Airport^[1][2] (IATA: ELM, ICAO: KELM, FAA LID: ELM) is in Chemung County, New York,^[1] seven miles northwest of Elmira^[1] and eight miles east of Corning. It is in the town of Big Flats but its mailing address is Horseheads, New York. The airport was formerly Elmira Regional Airport.

Situated just north of the Southern Tier Expressway (Interstate 86), the airport serves the Southern Tier of New York and Northern Tier of Pennsylvania with airline flights, general aviation, and glider activities. Other airports in the area include Greater Binghamton Airport and Ithaca Tompkins International Airport, with Greater Rochester International Airport and Syracuse Hancock International Airport lying farther afield.

The airport covers 1,000 acres (400 ha) at an elevation of 954 feet (291 m). It has three runways: 6/24 is 8,001 by 150 feet (2,439 x 46 m) asphalt; 10/28 is 5,404 by 150 feet (1,647 x 46 m) asphalt; 5/23 is 2,017 by 150 feet (615 x 46 m) turf.^[1]

The airport had three paved runways about 4000 feet long in a north–south, east–west and northeast–southwest orientation in the early years, but the northeast–southwest runway was 4702 feet in length by 1960, was extended to 5604 feet by the 1960s with later extensions to 7000 feet and 7600 feet before its present length of 8001 feet. The east–west runway was extended to about 5200 feet by the early 1980s and the north–south runway was abandoned and the additional roughly 200 feet of the east–west runway was added by converting part of the overrun on the east end of the runway to usable pavement (for takeoff), but then the landing threshold was displaced about 400 feet.

In the year ending June 30, 2013 the airport had 22,164 aircraft operations, average 61 per day: 51% general aviation, 33% air taxi, 13% airline and 2% military. 33 aircraft were then based at the airport: 52% single-engine, 15% multi-engine, 30% jet, and 3% helicopter.^[1] Airport services include free wireless Internet, automatic teller machines (ATM), conference rooms, and a restaurant.

On June 23, 1967 Mohawk Airlines Flight 40, a BAC One-Eleven, crashed in Blossburg, Pennsylvania, shortly after taking off from Elmira/Corning, killing all 34 persons (30 passengers and 4 crew) on board.^[8]
