How often are BA/Iberia flights 100% full with more than one staff jump seater trying to get on? Pretty rare I would think so.......
Not that unusual at BA, whatever else they are bad at they seem to be able to fill the aircraft, every seat taken is quite common on the busy routes which often tend to be commuter routes for staff as well. I have left people behind twice recently on an aircraft with only 1 f/d jump seat.
All very well for our Willie, don't suppose he has much trouble getting on when he needs or wants to.
