Thank you for your quick answer!
This is a no brainer: Aegean/Olympic
This week Aegean have won 2 awards at the Skytrax World Airline Awards:
Best Regional Airline in Europe (8th time in the last 9 years) and Best Cabin Crew in Southern Europe.
On a short flight - who really cares? Aegean was OK at best.
Obviously it matters to some people.
