It's my silent comment concerning FR's route policy. Is there any logic in it?
Yes. As long as Ryanair meets contractually agreed pax numbers, the load factor as such is really not that important. They do not earn money from a full plane, but money from a plane two thirds full whose passengers are spending more money on priority boarding, luggage, credit card fees, travel insurance, on-board sales. And, first and foremost, they earn money from airports providing services for (almost) free and from tourist authorities paying for an airline service ("marketing support"). So more flights from, say, Tampere are unattractive as long as a full plane there does generate less income than a plane 2/3 full elsewhere.
