One of the easier ways in and out of LGA Delta to Chicago and DC daily
Not good. Avoid unless you can fly out of terminal A to Chicago or DC.
Not much in the way of food or drinks to enjoy while you wait, but the security line is often very short.
What a gem! Once home to the Pam Am clippers, now Delta shuttle. No more than 150 steps to security. Efficient. Easy. Like going back in time before airlines made travel suck
As far as airports go, you won't. Breeze through security quicker anywhere else.
