Hi ,
just a "mea culpa" note:
Iīve been working in Barcelona approach for less than 2 years, but I have to agree with you in this case;
Iīve seen a few controllers give priority to Spanish aircrafts over non spanish ones, I didnīt like it and told them so.
Most of the time is "the old guard" doing it.
I want to think that newcomers are a bit more aware of the service we should be providing and try to act accordingly.
Expect improvements in times to come
