There is no date set for Albania’s EU accession. It could take several years. Wizz Air will have known this. Flights between UK and Albania would have to be operated by a Wizzair UK aircraft. They do not seem to rotate aircraft through non Wizz Air UK bases, so I question what the plan was. I do wonder whether the original announcement, timed to coincide with Ryanair’s announcement, was a spoiling tactic.
