Apparently the catering on some flights is minimal even in business class. Passengers flying Lufthansa on flights catered ex-Frankfurt should prepare and eat in advance if they have planned to get some food during the flight.
You have to keep in mind that some flights within Europe are catered from the base both ways.
Lufthansa hasn’t made any announcements about this employee action leaving passengers in the blind. The strike is likely due to airline announcing that it would offload the catering unit that may affect employee benefits, wages and job security.
