TAP business class passengers are invited to use the SAS lounge at Newark, as they do not operate their own. The SAS lounge is so nasty, I'd argue that it might be more a better idea to skip it. Way overcrowded, poor quality liquor, meager selection of cold snacks. The place looks like an room full of Ikea reject furnishing. If you find a place to sit, it will not likely have a power outlet. WiFi so slow it is practically unusable. Really low rent.
