We paid $161 for two exit row seats thinking there’d be extra leg room and not be cramped! The price we paid was a rip-off for these seats and the plane was extremely narrow and cramped. The male crew were okay but not super-friendly. When we picked up our luggage at baggage claim, someone ripped my luggage with a knife or blunt object and destroyed it!! I will be filling a claim for this and took pictures. I heard great reviews about this airline but am disappointed.
