addasih I think there's a typo on your flickr pictures, registration is JY-AIB..
Actually we flew on the same plane JY-AIB, where (OMG?) seats are tiny like there is no tomorrow, for my return leg today I had JY-AIA, actually on JY-AIB, my knees were touching the seat in front of me, as on JY-AIA there was an easy 15cm in between my knees and the seat in front of me. Way better flight today!!
