I am not seeing a 330-300 on Seatguru that looks like the seating chart on delta.com for a DTW-AMS flight.

Delta shows me
Delta One 1-9
Premium Select 20-22
Comfort+ 30-32
Main Cabin 33-59

the A330-900neo map is closest but only goes to 58 as highest row number and shows PS as 20-23 and Comfort+ 30-36.

Trying to figure out if the first row of Comfort+ is good or bad, looks like on some A330 leg room is a bit limited due to bulkhead so leaning toward second row of Comfort+, which on the planes I will fly would be row 31.
