Not really, people went against the age limit of LH about 2 years ago and they dropped it from CAs, but I am surprised that they still have it for pilots.
The problem with LHITA is, that it does not affect many germans, as you have to be fluent in italian, so it would be on the italians, to go against it, as LHITA will be an italian company.
Anyway, the would still be an unofficial age limit and they have other problems at the moment.
Today is another pilots meeting and the LH pilots are going to fight against the recruitment of LHITA.
LH instructors already refused to train pilots for LHITA.
