Functional is probably the best description for this airport. The only reason I use it is for short business trips of up to 4 hrs rather than going to Hong Kong and back which is tiresome even if you are flying business class. Given all the investment in Macau they have really got to do something and quick to serve the travelling public better. There are signs that improvements are on the way but it could all be too little too late. The Immigration clearance is tortuous heaven knows what will happen if this airport really does go international and the passenger throughput increases substantially.
