It is no more unprofessional to deny CD in pursuit of our RP's than it is to utilize CC. It's a part of our profession and the only way to provide our GC negotiating capital to get our contract. Compliance does not have to be something you like, but it is a necessary evil to provide for our families. Harden the f#$@ up and join the team!
Why anyone would use CD on the 3 man European flights is truly amazing to me. Even a fully rostered daytime flight on bodyclock is too long to be safe with passengers aboard. The clock ticks for the disaster on that scenario.
