"Not good" ... Understatement of the Century! One has to look long and hard to find worse!
EK 777 J was almost acceptable a decade ago... now its the laughing stock of its competitors... maybe EK will blink when every other airline, however cheap, has a better offering.
That said, back in the day, I sat in the dreaded middle seat, on a few long haul flights ... but only when travelling in a group of three (and in the front mini cabin). If I'd been travelling solo, I would have simply chosen a different airline, no question, no hesitation!
