The onboard cellphone-cacophony-coverage will prevent me to fly LX in the future (also applicable for the A330/A340 routes for avoiding an equipment change). There are still quiet airlines around, and since I don't longer care for any status, I can (and do) deal with.

But I gave a "customer feedback" to LX and asked them how they handle this problem in different situations (night flights, day flights with off-switched cabin lights, video conferences etc.). Interested about their answer.
