I have recently been evaluating low-cost airlines based at STN and LTN. Without going into too much detail as regards their operations, it's clear that GO, Buzz, FR and EZY all cover an extensive route network.
In reality, are there any new potential destinations which are not yet served from either airports? Ideally, such an airline requires freqency, so perhaps serving smaller Spanish destinations, for example, are out of the question. What do you think?
In your opinion, what new destinations could be served from STN?
