We flew with SmartWings from Brno to Crete on August 9, 2018. First of all, the check-in service at Brno was outstanding. It's a small airport without the stress and crowds of larger, more busy airports. We took off and landed on time. The flight was uneventful, which is good in aviation. Our aircraft was a 737-800.
It was a hot day, and the flight attendants did a great job of passing out water to keep us all hydrated. They also offered free newspapers. Food and drinks were sold - at high prices. We didn't buy any, but a lot of passengers did.
SmartWings is a no-frills airline,and we expected nothing. Having said this, the attendants were very friendly and polite, and provided very good service. The plane was fairly clean. The seats don't recline much - which is a good thing, in my opinion (no crushed knees). Not much legroom, but that is to be expected on such cheap flights.
