Max length: ≤ 292 cm total (L+W+H).
Your board's length alone (213 cm) is under the limit, but this cap is on TOTAL length + width + height — add your bag's width and height before assuming it fits.
Within allowance (international)
On international flights no oversize fee applies within 292 cm total linear size, carried within your free allowance. On domestic flights a board over 158 cm incurs an oversize fee, charged per bag. Use a hard case; 32 kg max per bag.
