Old long haul J's downside is the table. Everytime I have to readjust my seat to upright to have my meals. Besides this,everything is cool especially those seats on row 86 (744 UD emergency exit seats). I used to sleep on row 86 better than in F!
On the other hand,the new J product is getting old again. B-HKT's 16A and 17A's armrests were out of order in Apr,hope they would be fixed during new Y installation.
I am ok with both seats if I am alone,however I would avoid 74A if there is any companion.
