The carrier did not give details of the routes, but mentioned US-flights to New York, Miami or Fort Myers from Duesseldorf airport as having a higher proportion of business travellers.
Until now, Eurowings offered only a "Best" fare, giving customers more legroom and the adjacent seat free.
The new offering will be premiered at the ITB travel trade fair in March, Eurowings said.
