Here's a picture of what appears to be an EasyJet plane being serviced by a jetway (enclosed gangway) at Alicante airport. Whether that's evidence that Bonzo3legs' photo is an exception, instead of the rule, I have no idea. But it definitely shows that not all EasyJet passengers flying out of Alicante have to wait in the sun. Maybe a jetway was malfunctioning. Maybe delays caused there to be more planes on the ground than there were jetways to handle. Who knows?
