DONTTELLTHEPAX. If you are correct and let us assume you are spot on with your "statistics", let us please bear in mind that these delays are the result of equipment failure, utilising other peoples equipment whilst awaiting delivery of Flyglobespan,s own equipment.
The airline's reliability on established routes would to my mind seem pretty good for what is essentially a low cost airline. Certainly compared to the much larger "Low Cost Airlines" based out of Luton or Dublin. Both these I have known to my cost just cancel flights when their equipment becomes unservicable, and leave you high and dry.
Flyglobespan would seem to be pretty darn good on the Edinburgh/Faro route for example.
