I want to know the answer to the following question:
What year did Olympic Air receive an award as Top Domestic Airline?
All the background I'm provided with is that "Both Aegean Airlines and Olympic Air have won awards for their services; in 2009 and 2011, Aegean Airlines was awarded the "Best regional airline in Europe" award by Skytrax, and also has two gold and one silver awards by the ERA, while Olympic Air holds one silver ERA award for "Airline of the Year" as well as a "Condé Nast Traveller 2011". Is that enough to answer the question?
Answer: yes
