New to Lufthansa and question on what is considered medium and long haul flights. I have been following the new press release from a few days ago but not sure about length of flight

For example NY to FRA is that a long haul or medium haul flight?

We are in business class to and from FRA and curious how these changes will affect our flights. A380 on the oubound and 747-400 on the return. As of right now anyway

Thank you
