When you notice a 7’ tall guy it would be great to get a emergency exit seat otherwise flight was a bit cramped but not your problem

Truthfully, this wasn’t the best Alaska flight we’ve been on, simply because of the delays that seemed to be no fault of their own. But they made up for us by giving us a free drink, which we were happy with.

This was the best flight experience I’ve ever had. Commendations to Yvonne for being so attentive in first class.
