You make an interesting point, but bear in mind one of the downsides of locos, i.e. flights canx.
Locos can and will cancel flights in line with their T&Cs.
easyJet have left me at an airport downline, closed their local office and gone home, saying come back tomorrow and we will try and fly you then.
It's in the T&Cs and there's nothing that you can do about it.
At least with a full service carrier, you can be reticketed on a different route, as I was by Alitalia last week - even though I did not appreciate the 4.5 hour queue, I did get to my destination the same day.
The only time I use easy on business is on a domestic route from my local airport, where they are the only option.
I find the experience pretty good, but no way will I risk a repeat of being stranded abroad again and if it was outbound, I might even be sued for breach of contract if I arrived substnatially late.
