8. Finnair A350-900 – Frequently Asked Questions
How do I know if my Finnair A350 has a mini-cabin in Business?
If your seat map shows two Business sections (rows 1–8 and 9–12), you're on the 43J version with a rear mini-cabin.
Which Business seats are best for maximum privacy?
Window seats 2A and 2L in the forward cabin, or 11A/11L and 12A/12L in the 43J mini-cabin. Avoid row 10 (near lavatories) and row 9 (only seat 9L, near galley).
Is Economy Comfort worth it on the A350?
Yes. Rows 31–34 (ABC and JKL) offer 34" pitch, giving 3" extra legroom over standard Economy, which helps on overnight flights. Note that centre seats (DEH) in rows 32–34 are standard Economy pitch.
Are there good Economy seats without paying for Economy Comfort?
Yes — seats 52A and 52L offer extra legroom at the front of the rear Economy cabin on both configurations.
