It is the flexability of ST tickets that is important over the price in many instances.
If you are late getting back to base and miss your ST flight it is no problem, you juet get the next, or nip to Gatwick and fly from there (in the case of Spain for example). This is not the case with Ryan, Easy etc - when you miss one of those flights it can be an axpensive experience indeed.
ST is rather important to commuters and vital to some believe me.
