Like most all US carriers (including some lower cost ones) they also are in CASS and KCM (letting you ride in the front when the back is full and making transiting security relatively painless). So commutes and staff travel is as easy as non-rev ever is. Their listing and check in site is fairly painless as well with unlimited D2 travel and 6 D1s per year.
I believe they have a no-foul double non-rev listing similar to Southwest for commuters also.
And PBS, easy trip trade, etc.
At present their medical is not as good as CX for US based FWIW but I’m not sure if it can be continued past retirement or not.
