The airport covers at an elevation of 954 feet. It has three runways: 6/24 is 8,001 by 150 feet asphalt; 10/28 is 5,404 by 150 feet asphalt; 5/23 is 2,017 by 150 feet turf. The airport had three paved runways of about 4000 foot length in a north–south, east–west and northeast–southwest orientation in the early years, but the northeast–southwest runway was up to 4702 feet in length by 1960, was extended to 5604 feet by the 1960s with subsequent 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, 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. Airport services include free wireless Internet, automatic teller machines, conference rooms, and a Dunkin' Donuts restaurant.

The airport also saw service from Capital Airlines, which merged with United in 1961; United dropped mainline service to Elmira in 1966. United Airlines offered regional flights to Chicago-O’hare starting from 2014 but the service was ultimately cut in 2016. In 2018, United served a new route to Newark. The route was eventually switched to serve Washington-Dulles, which ended service on January 6, 2020. Currently, Elmira is not served by United Airlines.
