I no longer travel monthly as I once did to attend meetings. Now my travel is pretty much confined to trips to see medical specialists and to visit a dying relative. I quit flying to funerals, rather see them alive one last time.
But when I do travel, I prefer to fly Alaska Airlines when ever possible. I have a few horror stories from flying other airlines (connecting flights) and I trust Alaska Airlines to make it right when there has been a problem.
If I am home sick, getting on Alaska Airlines always makes me feel like I an "home". 
United and Delta can take lessons from Alaska on how to treat customers and make things right.
