From the website:
Check-in at airports opens at least 3 hours before the scheduled time of departure.
I arrive JFK around 1.30pm, and EY100 doesn't leave until 10.40pm. Would it be at all possible to check in early, or would I have to wait till 7.40pm? I'm flying economy class.
I will have two bags to be checked, but JetBlue might be able to check them all the way though to Abu Dhabi. If not, I'll use JFK's bag storage location in T4.
