Finland’s Blue1 last month became the first regional airline ever to join the Star Alliance. A subsidiary of fellow alliance member SAS, Blue1 expects to complete its integration into the group by the end of this year. Formerly known as Air Botnia, Blue1 flies a fleet of nine Avro RJs and five Saab 2000 turboprops from Helsinki to 14 destinations in Scandinavia and continental Europe. The airline expects to carry more than 1 million passengers for the first time this year.
