I've NEVER heard of a 28inch seat pitch!
Are you sure that was an acurate statement Shareholder?

All below are for a 777.

AC - 32"
AeroMexico 34"
AF 32"
Air Newzeland 33"
AA 32"
BA 31"
Delta 31"-33"
Emirates 34"
Jet Airways 32"
KLM 31"
SQ 34" and 32" Depending on which 777
Thai 34"
UA 31"

Anyway, you get the idea. AC doesn't really offer more legroom than other comparable Airliners. Infact, they offer less seat pitch than a handful of airlines on their 777 product.
