I've updated
the spreadsheet with the comparison of premium seating by aircraft with the new 333 configuration being available. Fairly significant increase in premium seats (22% to 28%), with a bit more of everything. Best ratio of total premium seats, PY, and preferred seats in the widebody fleet; the 77L is still the highest proportion of J seats. But overall it looks like the new 333s should be a bit of an improvement for those who don't just want Y.
That being said, still a long way from what UA and others are doing in terms of their equivalent of preferred seats. This is only slightly more premium than the current AC fleet.
