although EZY are "bending" the southwest model to fit Europe, flights to LPA, TFS and ACE from London airports and SXF just do not get the "bums on seats" required to see the equivalent revenue. In the same time an aircraft does a rotation to Canaries (8h+) it could have done at least 4 sectors if not more thus doubling the income for the same amount of Crew duty.
I'm sure they could factor this all in, but this would make it unattractive to pax. I'm sure there's the demand, esp during winter but not sure it works in the low cost model ex Northern Europe.
Ex MAD is a different matter!
