Never. You work for the best airline on the planet and get paid gobs of money for the privilege. If you feel compelled to come to work and complain about ****, there is something seriously wrong with you that needs to get addressed and repaired. Yoga, booze, divorce, all of the above, whatever. But nobody wants to hear the overpaid, prima donna pilot complain about stuff. Especially your flying partner.
Easy with the KoolAid there champ!!
