Lufthansa will make an announcement this spring regarding the long-awaited renewal of its regional fleet, CEO Wolfgang Mayrhuber said earlier this month.

"We are currently in talks with the manufacturers. After that, we will provide details," he said. He did not indicate the size of the order or if it would include aircraft for its Swiss International Air Lines subsidiary.

Currently, LH's regional carriers CityLine, Eurowings, Air Dolomiti and Augsburg Airways operate 145 aircraft comprising 18 RJ85s, 19 BAe 146s, 12 CRJ900s, 20 CRJ700s, 40 CRJ200s, 26 ATR 42s/72s and 10 Dash 8-300s/Q400s.
