Third row, aisle seat for me, close to the front so I can get off quick, but a few rows deep so I’m guaranteed to put my roller right above my head. Right side because my left elbow sticks out less than my right when using my laptop.

Any window seat in business class - or if in economy window seat in second row from front

The aisle seat of the second row of any section so I'm fast to board (for overhead), fast to leave, and can put stuff under the seat in front of me.

Second row aisle starboard side.

Exit row or at least on the wing.

I’m European, so… EasyJet: 1A, other short haul: 1C, or 11/12 A/C (emergency row on Airbus short-hauls), long haul: 3-5C or D (ie business, but a few aisles away from the front.

aisle seat in the row right behind exit, legroom + recline
