The Primeclass Business Class Lounge at Riga International Airport is used by the airport’s major carrier, Air Baltic, and other airlines which offer a Business Class product to their passengers.
The lounge is always available for Prioritiy Pass holders and entry can also be purchased for 40 Euro per person.
The lounge is located in the Schengen departure area offering 100 seats (830 sqm) with open views of the tarmac and runway. A bar, food options, a shower and restrooms are available. Food quality and choice was mediocre, the bar was often unattended and people had to search for staff to be served. The tables were also not cleaned and cleared frequently and some were dirty for more than 20 minutes.
I found this lounge experience to be subpar and I would not pay the money if I had to. Sometimes it can be better to find a quiet and comfortable space in the airport restaurant to get a drink and a snack rather than using a poorly managed lounge.
