You need to bear in mind that it's common practice for one aircraft to fly several different routes, even in the same day. So it might do a short 2.5 hour flight in the morning, then do a longer 5 hour flight after. Also I'm not sure with lo-cost carriers that the crew will get a chance to disembark. The plane will be turned around as quickly as possible.
