There's a bakery there for morning breakfast
I like their cinnamon rolls and the ginormous muffins. Seriously like 6 inches across!
There's something like 14-16 gates--3 on the left side, the rest on the right. Jet Blue boards from the right, which is where the bakery is located. No idea if there's a bakery on the left concourse, as I've only flown into that side once.
The longest TSA wait I've had was 15 minutes. I was detained because I had something that looked suspicious in my backpack. I carry my coins to be pressed in a mini-M&M container that they thought looked like a weapon. Once they inspected the bag and saw what it was, we were on our way!
You'll be spoiled by the airport; so much nicer than LAX!
When you land, just follow the crowd to baggage claim. Jet Blue is usually at carousel 2 or 3 on the right. The carousel area can be pretty loud. The left side (Southwest's baggage claim) is worse than the right side in my experience. Claim your bags, then go right out to the curb. Drop-offs inner curb, pick-ups (uber, Lyft) outer curb, and taxis across the street
