I think the easyJet news is really positive and a vote of confidence in the airport. Rather than shrink operations in the face of so much uncertainty at the moment and some cut-throat competition from FR, our orange friends have decided to hold their ground.
I'm struggling to remember the last route easyJet dropped. It's definitely been a while and I do recall several contributors claiming that SEN had one the worst records for routes axed by the LCC 2 or 3 years ago.
