Niki Luftfahrt is replacing its Embraer 190s after the regional jet was introduced to the Airbus A320 fleet only three years ago.
The Vienna-based subsidiary of Air Berlin has seven E-190s and three outstanding options for the type.
Niki confirmed the removal to Flightglobal but did not provide any details about the timeframe, the reason for the decision, or how it plans to replace capacity.
Aside from its E-190s, Niki operates a fleet of 12 A320s and four A321s, according to Flightglobal's Ascend online database. Four more A320s are on order for delivery by the end of 2013.
The airline's first E-190 was built in 2009 and delivered in May of that year. The most recent aircraft was delivered in May 2011.
