Southwest new boarding - how the heck?

[mrsstats]

For some reason the noise at the back of the plane is worse for my DH than the center of the plane. Flying in the back gives him a migraine. He prefers to sit in front of the wings, not all the way in front of the plane. Being a high stress person, it is better for us for him to sit in the place he likes. I know, fly an airline with assigned seating. But cost and location is the reason we fly Southwest. We stick to the rules about boarding and if everyone else would, things would be fine. I am sure we could pre-board since he has a heart condition and a fused neck. But he doesnt feel that he should when there are people who truly need to pre-board.
