LaGuardia has EMAS on both runways. Delta currently operates 767-432/ERs out of LaGuardia.
So does Bob Hope Airport (Burbank), which was prompted by the other Southwest 737 crash. Bob Hope sees FedEx and UPS A300-600s landing every weekday on its 6,000 foot east-west runway. FedEx occasionally flies the A300-600 into John Wayne Airport (Orange County), which has only a 5,700 foot runway. Takeoffs from John Wayne are even more spectacular, given the need to climb rapidly due to noise restrictions over the Newport Beach area.
Only on one end each - the other arresting agent is H2o.
