Lounge in Oslo is not an Air France lounge and only opens at 5:15, one hour before departure of the first Air France flight of the day to Paris, required to make the connection to San Jose, or pretty much anywhere else for that matter. That lounge is not great. No showers. Dated. Limited food options, which is usually not an issue as food on Air France in Business Class, even on European routes, is the best in Europe.
