It isnt really that hard, their logic is: we have got staff to fly X routes, lets fly X routes that are uninterfered with instead of flying some routes whom have regulations and fees placed upon them. Its really quite simple, doesnt matter if the price for a ticket is equal to a bus ride or equal to an own private jet. An increase in price for the customer will inevitably lead to a decline in demand for that particular product.
Airlines based in Sweden canīt really cut down and move capacity as it would mean a significant change to their main market whilst for airlines as FR its nothing except a moving capacity to more profitable markets.
FR is currently struggeling to staff their aircrafts and will therefore need the capacity at the right place at the right time, therefore they will want to move their airplanes (read crews) from routes such as VST and MMX.
Itīs quite clear to me what they are thinking, and whilst you may not think its right, I belive its correct in a business perspective.
