As a result of the pilots' strike at Eurowings, the Lufthansa subsidiary pulls out the red pencil.
The fleet of 81 aircraft planned for 2023 will initially be reduced by five, the company announced on Tuesday.
The planned creation of at least 200 additional jobs at Eurowings Germany in the cockpit and in the cabin will be stopped with immediate effect.
Pilots who are currently in training are only given temporary contracts.
As the demand is reduced, all promotions to captain will also be stopped, the company said.
In a bitter collective bargaining dispute, the Vereinigung Cockpit pilots' union and the management are fighting for relief for the pilots.
Numerous machines remained on the ground again on Tuesday.
Among other things, the union is demanding 14 additional days off.
Management recently offered ten.
In an open letter to the workforce on Monday, management threatened to withdraw the offer if the strike continued.
Because of the strike costs - according to the company a two-digit million amount per day - jobs are in danger.
An ultimatum on Monday evening allowed the union to pass.
With the announcement, the company is stopping its growth plans for the Eurowings Germany, which is on strike.
It did not comment on Eurowings Europe, which was not on strike.
