There are probably 50% of my new hire class, 26 years ago, who have never upgraded to the left seat!
They are flying ultra senior WB f/o, enjoying all the bennies of those positions!
Also, 1/3rd of our class has moved back to WB f/o for the very same reasons.
I might entertain the idea of A350 B as my retirement position, if I can earn (almost) as much as I do now!
