Pros: I've never been on a flight with such narrow seat and thin cushion. There was no entertainment offered for the almost 4 hour flight. There was no means of charging any electronic gears. The airplane seems to be 30 years behind time. Crew was unfriendly and smiling faces are not part of the uniform.

Cons: Very narrow seats and thim cushion. No entertainment offered an do means of recharging electronic devices.
