This is a scathing article giving more background to the rights the unions are fighting for.

I had been trying to independently figure out how much their ticket fares have gone up by comparison, and a ballpark number from some spot checks from documented fares in that period as compared to today are (very roughly) +20%.

So inflation from 2023 to 2026 is 19%.
Ticket prices increased by 20%.
Pension contributions increased by 0%.

Yeah I can’t side with Lufthansa on this one.
