I believe the TAG Asia situation is a bit "muddled" at the moment. For the last few years all the operations were technically under TAG USA, which was recently needlessly evicerated by the FAA. TAG USA sold out to Sentient Jet in the US. I believe the TAG Asia contracts are being taken over by TAG Switzerland?
A friend working on one of the TAG Asia contracts recently lamented the current lack of general oversite of the contracts by a "serious" TAG entity.
TAG Asia is based out of Hong Kong and doesn't really have the operations and support personnel to administer the contracts.
