JFK check in

Thinking of changing my departure airport on Monday and am just wondering what time check in opens at JFK ( and more importantly the CH ) .
Thanks,
DL

Officially check in opens at 14:15, but UC check in opened closer 14:30 when we were there the other week.

The CH opens around then, if not earlier

Thanks Hamster.

You will be taking off from JFK just as I am landing from LHR!
