J and F LH onboard flight has been way better than UA, but everything else has been a hot mess with LH:
- They delayed my luggage 4x 2022 Nov-Dec (returned within 3 days each time)
- EU claims took 3+ months to process. One didn't process until I filed a claim with both DOT and Schlichtungsstelle für den öffentlichen Personenverkehr.
- Phone agents are only for ticketing and would not help with any issues post travel
- I was downgraded from F to J once and they only offered me $300 cash even though the difference in fare was almost $6k. (ended up cancelling the ticket)
- good luck getting their app or website to let you assign a seat
- Also changes to itinerary or seat don't reflect in LH app, one time I boarded only to find LH changed my seat and my digital boarding pass didn't reflect the change
I only continue to fly LH as its the only reasonable option to get me between SFO and GVA most of the time, or I am booking last minute and F is available with points. United tends to be 2x the price otherwise.
