Which seats have air belts on the A321 K/R?

• A. FC seats 1 AC and Row 8
• B. 2L and 4L
• C. 1A and 2A
• D. All forward cabin seats

Answer: (A)

Air belts are not standard on every seat; they’re installed only on specific seats in this A321 K/R configuration because of certification requirements and space around the doors and galleys. In this layout, the inflatable belt system is fitted to the First Class seats in row 1 on sides A and C and to the seat in row 8. Those positions are where the hardware and deployment of the air belt can be safely accommodated and certified.

The other seats listed don’t have the air belt hardware installed in this configuration—either they aren’t part of the approved air-belt subset, or their location elsewhere in the cabin isn’t compatible with the system. Saying all forward cabin seats would imply a blanket installation that isn’t the case here.
