It’s been a while since I’ve done LH European J class but I did like the fact thst on the E190 out of LCY there was a seat blocked off next to me whereas on the BA ones it’s not.
Currently looking at 10 rows of CE on flight to LCY next month am going towards the back in the hope thst people will want to sit closer to the front giving me the chance of a free seat next to me.
