Flew RAM MAD-CMN-IAD in business last month. It was fine. The service and seats are equivalent to TAP. We are finishing that ticket JFK-CMN-VLC with a 5-hour layover.
We didn't visit the lounge at CMN flying west, but I understand it's not so great. Does anyone know if there's a better place in the airport for a nap after the short redeye from NY?
