I just booked a J and F seat from JFK - HND on JL3 for October 2025. The seat map currently has the two first row seats in F block. Can I assume this was done purposefully since the plane/ seat map is the 777?

Based on everyone’s input above, it looks the JFk route should be using the A350? If so, any idea when the updated seat map will be made available for accurate seat picking? Thank you in advance.
