If you assume that at the time RYR make decisions to start routes they use the best opportunities open to them the list of cancelled routes particulalry out of STN makes grim reading. What it means is that RYR is reaching the limits of its current business model. It means that the routes canceklled simply cannot make money at any price at which tickets are sold. It does not matter whether ticket prices are high or low these marginal routes are incapable of making money even for RYR.
As London is by far the largest air transport market in the world it means that RYR is running out of profitable opportunities from London unless it gets into big airports in Europe. On this basis there is simply no way that it will find profitable opportunities for the 2 aircraft per month tht it has ordered for delivery over the next five years.
IMHO EZY is likely to prove to have the better business model as it has found it profitable to operate into major airports. Sure this is more expensive but the public seems well prepared to pay for the convenience.
