My apologies - I checked your exact dates and you do have the older style 2 x 2 seats. It looks as though some dates have the old and some the new - is there a chance for you to change the date by a day? It might be worth it if you've got the time.
The 17th has the new seats.
The 19th looks like is "sold out".
Your flight has 9 of the 12 seats taken. Window rows 2 and 3 on the right and window seat 3 on the left are open.
