Referring to the initial question...
had previously served CTA
But they decided to leave because the airport authorities were not able (or willing) to undertake any measures to reduce delays originating from the ground handling.
had a very good loadfactor/yield on the flights to CTA
but the constant delays of the a/c at CTA
was spoiling the on-time performance too much!
can´t afford constant delays at an airport if this means they can´t maintain the calculated number of flown legs per aircraft per day just because an airport is unable to cope...
This was a rather unusual situation in the LCC-industry but FR
had no other choice!
promised to return to CTA
if the airport authority guarantees on-time ops.
So far they did not promise...
