I honestly believe the majority of passengers on low cost airlines (including myself) just see the journey as a means of getting to the destination, safely and as near to on time as you could hope.
If you don’t set out with any expectation you won’t be disappointed.
If by using low cost airlines especially on Europe it means I can afford an extra holiday or visit then I will. Business travel should never be confused with the two. When I travel business the time I travel and the potential state I am in when I arrive are important.
However if my destination is a sun lounger in the Mediterranean recovery from any journey is a pleasure.
