I don't think there are that many other airlines out there to come onto the routes.
Perhaps Emerald will make yet another return when their contract expires. None of the LCC would come here unless they were paid as there is not enough business and the airport charges are too high.
Some sort of user agreement with strict controls on frequency and fares is what is really needed but I would not count on the position changing until after the election in November.
EM's performance last year really worried the Government and it will take a long time for the confidence to return.
