I find it hard to see new routes being announced soon, unless it's EI or FR trying to get a bit more effective returns from their base aircraft (i.e. reducing frequency on other routes to do it).
Maybe Wizzair might add a link to another of their Central European bases.
Maybe, Aer Lingus Regional might add another aircraft. It would be handy in terms of frequencies to Birmingham and Manchester, which are back down to one a day.
But I'm not holding my breath.
