I'm gonna join the nope group too. I'm 6 foot 3 and I'm fine in a normal coach seat.

The problem is that most of Alaska's flights are so short that an E+ wouldn't work. UA is an international carrier with MANY long hauls...AS on the other hand has the bulk of its flights as short haul west coast flights. It is easier to justify paying for more legroom on a longer flight, than a 2 hour hop down to LA.

Besides UA has less pitch in E-, and the economy cabins are much worse off...

I know it sucks to be stuck in a middle seat, but seats do open up. If you really need peace of mind you could always choose another flight, or even worse...another airline if it makes that much of a difference.

Why would AS want to copy a feature from two airlines that are both almost dead??

Alaska is a very well run airline compared to the rest, and obviously they have to be doing something right
