The good news that Wizzair will soon be having up to 11 departures from Luton some mornings between 8 and 9-ish also means that the already at times severely-strained security facilities there will become even more overwhelmed.
Wizzair has a good product, cheap flights, and a user-friendly website. It provides a service to some otherwise-quite-tricky-to-get-to-places. But its success needs to be acknowledged and managed by the airports to which it flies.
Take Bucharest's tiny Baneasa Airport from which I recently took a Wizzair flight when another Wizz and three Blue Air flights were leaving within an hour. Shocking delays at security, purely because the infrastructure and management were not geared up to handle five hundred passengers at once. I hope Wizzair is working with airports to address this issue, as otherwise passengers will be dissuaded from flying with them.
