Done my CPL, ME, IFR and PBN with EAS Barcelona.
And for a brief, i was a worker in EAS.
Incredible school, great management, excelent fleet and all labor personel truly dedicated and professional. If they say you will finish a module or a cours in "X" time, i guarantee you this time will be not prolonged cause the "weather" or "maintenance" (and you know what i mean). Quality before quantity. That's the winner bet they did with great results.
About OneAir.. well, based on an ex-worker i 100% trust in his word..run away, and run away fast.
