Lufthansa signed a firm order last month for 12 Bombardier CRJ900 regional jets. Once it accepts delivery, the German flag carrier plans to use the airplanes to replace 50-seat CRJ200s flown by Lufthansa CityLine. However, Lufthansa’s pilot union has yet to agree to a new scope clause that would allow the 86-seat jets within the CityLine fleet. CityLine’s 18 Avro RJ85s leave that subsidiary with no further scope to add regional jets certified to carry more than 70 seats.
