When are you going?
Loads around Passover can get pretty bad. On the other hand (if you aren’t Jewish), flying directly on the holiday can workout nicely.

Getting out usually isn’t actually that bad. The flights line up pretty nicely in the evening. The UA to ORD or IAD are after midnight and so are a couple of the ElAl flights, so you can almost bank on at least one or two families showing up for their flight on the wrong day.

They won’t let you go to the gate until you have a seat. They make you wait it out at the ticket counter outside security (at least as of a few years ago). It’s a bit unnerving knowing you are 45 mins from departure and still need to get through security and customs, but the timing works out.
Last minor tip… they take your liquids away at the gate and not at the main security, so don’t buy a bottle of water to take on the flight with you.
