Majority of those links are broken. There are some working links on the page and a few of those are links to the ones available on Avsim and Flightsim.

However, there are still some major liveries for the 300 series missing and it just doesn't feel complete without them.

Upon checking AVSIM there has been a new livery uploaded by Jeremias Marco of a Star Alliance Singapore Airlines.

I'm currently doing RKSI - WSSS With it now, it looks fantastic. I hope these uploads become a common thing.

:) :D
