About a decade ago, when I flew corporate, sat at the bar with a retired legacy US legacy carrier pilot. He had always been able to do long haul, but most not senior enough to be pilot flying. He estimated he had done around 2 landings per month in the last 20 years of flying part 121, so about 500 landings in that part of his career. I had just come of flying ACMI for a European regional, doing 10 days on 5 days off, 6 legs per day, and in 8 months had about 500 landings as PF that year. He also had 8000 hours "dozing for dollars" (sleeping in the crew rest quarters as PIC). While I was commuting from the us to the EU I definitely flew more miles as a passenger than as a pilot....
