So I flew LH F last week and I made a comment to the FA's and sent an email to LH and this is the reply:
........In the meantime, we have also received a reply back from our Frankfurt Catering Management Team and unfortunately all our kosher meals are Sohar for all our flights departing from Frankfurt and there are no plans to change in the near future. Rest assured that your constructive criticism has been documented for future reference.
We regret that we were not able to meet your expectations; however, it is our hope to serve you in the future under more pleasant circumstances.
Sincerely,
Anita Ayala
