I booked through Kayak, trusting them. But they used one of these cheap online travel agents - Chatdeals. When I missed my flight due to a 3 hour train delay that was out of my influence, Chatdeals refused to rebook without a fee. SAS couldn’t rebook either. So I was stuck and lost the flight. Had to buy a complete new one. Never book through kayak or one of the cheap ones. Always airline direct! Expensive lesson learned… 🙂 Jan

On this particular flight, the staff were quite unmotivated, the seat legroom was adequate, other than that the flight was uneventful.
