Lufthansa’s inflight entertainment system is notorious for being unresponsive and difficult. 10 years ago its difficulties were acceptable but now, with technology as it is, it’s just cheap. Shifting from a general comment to one specific to my flight: the food was odd and bad and the boarding was surprisingly chaotic for Lufthansa
