They had wasted so much money on the failed Star Liner restoration project before that now the upper floors feel like they can't pump in any more money in historical aircraft that are not as reliable as current airliners. Plus Lufti is set to become more european. Their brand Eurowings will take over more business and Spohr seems to be prefering to take down old brand elements like their 100 years old yellow from the logo. It's transition not tradition.
