I recently upgraded to First Class on a night flight and I'm on an AA 737-800 seat 1F at a bulkhead. Should I change my seat? What are others experiences in First Class on AA?

What other seats are available?

Domestic F gets you a bigger seat, unlimited drinks, and a few passes of the snack basket (there won't be a meal service for a late night flight).

1F doesn't have the best leg room and you will have to stow you personal item up top, but you have the benefit of no one in front of you. I personally like 2F the best.

Without knowing the length of your flight. You may or may not get a pre-takeoff beverage depending mostly on the mood of the flight attendants. If it is a short flight you will get drink service after takeoff plus a selection of snacks. If it is a longer flight you should get your choice of breakfast, lunch, or dinner based on departure time. Otherwise, you will mostly get a bigger seat and a little better service from the FA's.

One of my favorite parts about the 737-800 first seat is there is a little storage cubby under one of your arms that will hold a phone, table, or small laptop. Unless you are really looking it is easy to miss.

As much as people like to complain about first sometimes, it is much better than coach. Enjoy your flight.

I like seat 1F, but I don�t mind the bulkhead. I�m also not very tall (5�9�). So I like that I�ve got the side of the plane to lean against but I still get out of the seat without waking my seatmate (usually). Don�t expect much in the way of service on a redeye - there is not a meal expect on premium transcons (which are not flown with a 737). Drink service and a pass at the snack basket after takeoff.

Tell us your flight number and we can tell you what to expect.

OP do you mean a trans con red eye flight or simply an evening flight like DFW-IAH?

For some reason, all the seats on the left side of the plane are available (1A, 1B, 2A,2B,3A,3B, 4A, 4B and 4E and 4F

AA 1608
It is ORD-DCA.

2E seat is occupied.I'd rather not have a seat mate

You should expect all the seats to be filled (especially in domestic F), so I wouldn't worry about which seats are occupied vs vacant.
I'd select a non-bulkhead row because bulkhead legroom is restricted and on such a short flight I'd like access to my bag.
You can expect free drinks and a pass of the snack basket with gourmet items like chips ahoy

This is my most flown mainline route. No meal since the flight is under 900 miles so you'll get free drinks including alcohol and snacks which are things like small bags of cheez its and ruffles, so you should eat dinner before you board (or wait until DC, but depending on the evening you might not find much there late at night). You'll most likely get a good number of refills if you want them, as long as it's not super turbulent. Feel free to ask the flight attendant if you want a refill.

Lots of elites on this route so barring something crazy every seat will be full from upgrades; I would pick the non-bulkhead but it doesn't make much of a difference. I usually go non-bulkhead so I don't have to worry about boarding early to find a good spot for my laptop bag.

If you're flying Tuesday see you on board

I like the bulkhead seats. It gets you off the plane first. YMMV

You are correct, though I note my own negative experience one time when someone in a row 2 aisle seat got really annoyed and verbally belligerent when I, in 1F, stepped into the aisle to get my bag and get off ahead of him.

Personally I would pick 1A or 1F on this flight. I don�t usually need access to my laptop bag in flight.

The bulkhead is a preference thing, you either like it or hate it, I personally prefer the second row, I fly the route a lot and first is almost always full, 7 days out you will begin to see upgrades clear and the cabin will begin to fill up, in all honesty these days what first gets you is a slightly larger seat, quick access to the door, early boarding. You may or may not get a pre departure beverage this is really crew dependent these days.
