Hardly. EasyJet have tried and subsequently dropped Inverness, Southend, Prague, Berlin, Venice, Bergamo (albeit a bookable charter), Malta, Rome. Experiments currently ongoing : Split, Jersey, Arrecife, Bordeaux, Jersey, Lyon.
When EI arrived at BFS they largely duplicated Easy's international routes and got their fingers fried. That forced them into experimentation. Their failure at BFS had little to do with the airport and plenty to do with a strategic cock-up. They now have a niche at BHD and that's fair enough.
