I wasn't making any points about upgrades or anything like that, because it's a one-class service, and as the only cabin service is what you buy there's no issue there either. But to be sat squashed in, separated from colleagues who were slotted in around the cabin while there were plenty of empty seats fore and aft, is just a lack of forethought. I am sure that if they had 120 pax rather than 50 on the sector they would have happily used all the seating, and on any other such low load factor I have flown in the past people were well spread around, as we all know happens. You accept it if the flight is full, of course, or if you pay Ryanair-style fares, or if they had substituted a 50-seat Embraer instead, you will have to sit with your knees up by your ears. This one was two-thirds empty.
