Interesting conundrum: picking essentially between middle, aisle or window seat.

Even though it is a bulkhead and has some legroom and allows you to get up to access the aisle, I probably wouldn’t pick 30F since it is a “middle” seat. Only if all my choices were middle.

Personally I like window seats to both look out as well as having the wall to lean against. But for a flight that long tryin to get our and in could be a problem.

The aisle seat/exit row would give you easy access and good legroom. But being close to the lav/galleys and not having a wall to lean on or view outside the plane would be a negative.

So depending on what you value most, either 34J or 45C?
