Tried to do a search but could not find existing topic...

It's a complaint...

Took Cathay... Sydney-HK-Seoul and return in Economy.....

Found that leg space is severely restricted by
1) TV/Video equipment under front seat... Cannot stretch legs completely...
2) When closed, the foot rest seems to close too high and the knees keep
hitting it....

Is there some website on comparison of leg space between airlines??
