Air Baltic flies twice a day between Brussels and Riga, capital of the Republic of Latvia. Air Baltic is a real low-price airline and surely not only to Baltic destinations. Top destinations are e.g. 7 destinations in Finland (including Lapland), Saint-Petersburg, Moscow, Minsk, Kiev, Tbilisi, Yerevan, Baku, Tashkent and Dushanbe. Destinations which are not frequently offered with other airline companies. Air Baltic is therefore a real niche product and often also very cheap.
We recommend you to take the Flight Selection travel insurance of Allianz Global Assistance (from €22 within Europe and from €52 worldwide).
