The Bombardier CS300 delivery was much anticipated by airBaltic since this new aircraft type was originally planned to replace most of the airline's Boeing 737-300s and Boeing 737-500s and now will replace all by 2020. The delivery of the CS300 happened on 29 November 2016, at 2 am ET. On 28 November, Bombardier and airBaltic held a ceremony in Mirabel, Quebec, Canada for the first delivery of the CS300. At 1:30 am, shortly before the scheduled departure, an oil leak from an engine was spotted. It delayed the departure, but at 2:23 am ET, the aircraft was now airBaltic's property. On board the inaugural flight, there were 18 people, including 6 pilots: 3 from Bombardier, and 3 from airBaltic. At 4:13 am ET, after a delay of over 2 hours, flight BT9801 took off en route to Stockholm. The airline received two CS300 in 2016 and expects to receive six in 2017, eight in 2018 and four more in 2020.
