Flightrider
It exists, trust me. It’s dependent on time of the year, routes and markets but easyJet offloads an average of 14 bags per sector.
EZY crew do manage it better than BA crew form my observations of BA flights too but easyJet crew have had years to master the art and that requires crew to be actively involved. Even so, last minute offloads are a big source of customer dissatisfaction. This is also why there isn’t an option to purchase this extra allowance, it is linked to certain seats and plus card holders. Had it been possible to purchase extra allowance it would defeat the object of the new policy and that would certainly be a case of profiteering.
