Anecdotes aren’t data, but in 2018-2019 I was getting really sick of deadheading constantly and flying 5 day trips with 3 different CAs.
My block hours on a trip were probably down, but not my time riding an airplane. But hey, if the company decides that’s how they’re going to build trips…
(Actually, I hated all the DH time. It’s not like I was getting first class seats, or even comfort+. And DHing just gets annoying anyway.)
