french atc
The assumption by some aircrew that certain airlines or traffic gets undue priority from some ATC operators always amuses me, as it betrays their complete misunderstanding of what is involved in organising a heavy & complex traffic loading.
Quite simply, ATC do not have the time or volition to rearrange traffic to suit favourite airlines or nationalities.
To do so would result in extra & an unwanted & complicated workload, & make a challenging situation even worse.
In 30 years I never did so; & I never witnessed any of my colleagues do so. Although, I did hear of one ATCO who avoided the stack at EGLL with a favourite airline of his, & he received a demotion as a result.
