I avoid LH metal now due to their tendency to meltdown during strikes, weather issues, etc. On board I find the crew generally good, the food fine (slightly better than UA but not as good as OS), and their C seats sub par, but acceptable on the 7-9 hour flights I have taken with them. I really like their lounges, but can use them flying any *A carrier. What keeps me from booking LH flights now is the absolutely unacceptable negligence they show during IRROPS, including it taking hours to get their to their reservation agents to change flights (calls are regularly dropped when caller volumes high), agents not empowered to make flight changes if you do get though (need to submit the changes to LH ticket desk, which responds after 6 hours by canceling the new flight leaving no alternative), no ability to rebook flights in the app (there is a button to choose from a list of alternative flights that leads to…a blank screen), and a chatbot Eliza that is also unable to rebook in case of irrops. I see LH on a downward spiral right now, and their labor woes will only make things worse. I feel for the crew, who deserve better management.

I have just been on LH intra-european flight, where plane departure was delayed for 2.5 hours because somehow for several passengers who were automatically rebooked with their connection flights due to initial (short, equipment-related) delay, they were removed from the flight they have already boarded and been sitting in their seats for an hour. They couldn't fix their IT system for that long, and they obviously could not fly with the passengers who were not (according to the system) on the flight.
Those guys seem to be really not doing well.
