Ah yes, fair comments.
The 738 service leaves a -lot- to be desired. With the new "the business" seating now pretty much entirely rolled out to the 332's there is a vast gaping chasm between 738 J and 332 J, yet pricing is the same. If they want to maintain the 738 version of J they'd be more truthful to start calling 'the business' style J domestic first class (or similar). Theres almost nothing to like about 738 J imho ... seats are wider sure, but extremely uncomfortable, a problem exacerbated by the lack of footrest, no J 'cabin' ... that little purple piece of dividing plastic doesn't count in my view, inadequate recline, poor drink/snack/food selection which borders on farcical given the usual price asked. Lounge and priority bags, boarding, screening etc works well, as it should, but as others have said, this is provided for status holders anyway.
Theres 8 J seats on the 738's and I hardly ever see them filled ... they'd be a lot better off in my view converting the fleet at the next refresh to 4x J seating of a style somewhat reminiscent of the current 332 'the business' and putting up a proper J cabin partition.
As it is, I won't consciously choose 738 J over Y unless something very special happens with pricing (as it did for me in one direction recently on a trip PER-DPS)
