Checking baggage is silly. You have to print your tags, and then you have to talk to an actual human even though you printed your tags and already answered all the questions, and they will yell at you if you're over weight for your bags or if they're not closed properly or you have locks, etc. Slot 20 minutes for this process because it's also different between each airline and each airline has its own area for that, and each has different levels of staff.

Second is that security here sucks. I'm not saying that it isn't effective, that's a different conversation and I might also say that, but dealing with it as a passenger blows. In the EU y'all are pretty sensible about security and the flow is pretty fast. Here expect to spend a minimum of half an hour waiting in line to get through security, more likely a full hour if it's during a busy time of day. Expect to empty your bags of all electronics, take off your shoes, belts, jackets, then you get scanned by a full body scanner where someone in a room looks at a 3d model of your junk but mostly just checks to make sure you're not covered in weapons like John Wick.

After that a bunch of people who have no idea how to queue will dive in and hold their bins preventing your bin of baggage from coming down the conveyor to where you're standing, shoeless and beltless, and maybe there is a chair to sit in to put your shoes back on you only have to walk 3 or 4m for. You're expected to re-pack your bags in front of the conveyor which is the least efficient use of time and space ever.

At this point it's probably been close to an hour since you got to the airport, you're finally through security, wearing shoes again, and have your carry on luggage. Now you have to get to your gate. The airport will be familiar to you if you've been in any other airport ever. If you're coming from outside the US you will note that most airports do not have smoking lounges. This might be ok for you, but it might be incredibly irritating if not. If you're lucky you're in a smaller airport and finding your gate is easy. Larger airports it can take a long time to get to your gate, especially if you made the mistake of going through security for the wrong terminal which they'll totally let you do. Sometimes that means going through security all over again, sometimes it means taking a shuttle or walking between terminals which takes another 20 minutes or so.

The rest you'll be familiar with, except boarding is a bit more of a shitshow with everyone standing up and queuing up as soon as boarding is announced instead of waiting for their group to be called. There's usually enough space in front of all the gates for all the passengers to hang out, and you almost certainly won't have the experience of getting on a shuttle bus from the terminal to where your airplane is parked on the tarmac.

As for the flight itself, if you've flown in the EU be prepared for a slightly nicer flight experience. The flight attendants will be more friendly, and the plane will both climb and turn at less steep angles than you're used to.

Deplaning and picking up your luggage is pretty much the same as everywhere else. Just wait for your turn to get off the plane, go to the carousel and pick up your bags, and leave. No passport control, ID, or customs.

TL;DR: budget an extra hour for getting through all the airport bullshit on departure, otherwise it's functionally the same as whatever you're used to.
