According to http://www.hfw.com/ASEAN-liberalisation-open-skies-achieves-full-ratification-May-2016 http://www.aseanbriefing.com/news/2015/01/02/asean-open-skies-policy-implemented-2015.html , ASEAN-SAM now provide 3rd, 4th, 5th freedom but without right to cabotage in ASEAN, with the limitation that Philippines have excluded MNL, Laos have edxcluded LPQ and VTE from airlines from Thai, and Indonesia only opened up a few airports.
Suggestion of implementation of the ASEAN-SAM into the game:
-Start with Yamoussoukro Decision
-Ignore the Laos restriction to Thai airlines as that is too specific
-Ignore restriction on MNL that’s put in place because of slot restriction as said by PH government
-Exclude Indonesia from the agreement as too little of Indonesia have been opened
