I have used Cardiff a few times to fly air transat, klm and ryanair and the airport looked so out of date to me. The departue jetway used on my air transat looked like it was made in the 1950's. On the way back with all the airlines I have flown with, the amount of steps and the design is bad. You go up steps to get to the arrivals walkway, then up steps to passport control and then down steps to the bag area. It needs to have a new design of building before trying to get other routes.
