As well as the 737 DEC being possibly the hardest job in the company (think China and domestics with lots of deadhead time and fresh FOs), it is also paid about $3K/month less than the 777, 747 and 380 positions, but is now the only way onto a wide body in KAL if you don’t have previous current widebofy experience (330 NTR expericed 320 positions are no longer available).
