Yup, this past weekend was an absolute debacle in JFK... but runway 22L/4R opened this afternoon so hopefully that mess is less often for the summer. Usually when the doody hits the fan there, things just end up cancelling because the delays rapidly exceed even the 2 hour extension. Fine for line holders with pay protection, sucks big donkey nuts for reserves that find themselves working 12 hour days for 4 hours credit because they have no pay protection.
