I'm not involved directly in the industry but I have seen no evidence of FR being in commercial difficulty,at least relative to the whole trade,and from a passenger point of view think it's great we now have an airline with the clout to influence pricing policies at airports and even governments.After all,we pay airlines for our travel and those outside the industry have no interest in the latter two hiking our costs.
I'm quite sure "No RYR for ME" is correct that this is exactly what he suggests,a form of punishment.Interestingly,the three airports he mentions are all in crisis in terms of route/passenger losses,and two have made massive capital investments which are now under-utilised.
Those who await a backdown may be disappointed when it doesn't come from the airline.
