Easyjet have clearly been aiming at business travellers for a while now. Their advertising of "convenient times for business from city to city", even the onboard coffee being Starbucks Instant instead of something more generic (Kenko, I think, before) and a choice of types of tea and so on.
They could improve a bit by having less crack-of-dawn UK departures on the shorter hauls and a bit nearer start of workday (i.e. 0900), and their punctuality over the summer was shocking.
Currently we're in the lull between winter (and lack of operational excellence and bad weather) screwing the schedules, and summer (and lack of operational excellence, southern European air traffic control, and lack of crew) screwing the schedules. I eagerly wait to see if this summer is as much of a cluster**** as last summer.
(Currently I am flying Easyjet at least fortnightly somewhere)
