I was on hold for 1.5 hours, got disconnected.
I called back. 2 hours later I finally get to talk with someone and after explaining situation for 30+ minutes (stuck on LI due to snow, no service to JFK, want to change flight), here is what he suggested: "You should go to airport and check in like normal". Really?!?
A half hour later I canceled my flight in frustration.
I fortunately found another flight on another carrier on the 29th. Only a couple hundred more expensive.
