This cover above is self-made, and I sent it personally from the Macau Airport post office. The souvenir sheet celebrates the tenth anniversary of the national carrier, Air Macau. Personally, I was so surprised that such a small country actually had its own airline and was even more surprised when I learned it had another carrier, Viva Macau, the first long-haul, low-cost carrier in the world. However, Macau is indeed a transfer point for Asian and Chinese destinations, as I came to learn, so the two airlines actually have a large customer base.
A little more on the Macau airport:
The Macau International Airport (澳門國際機場 or Àomén Guójì Jīchǎng) is situated at the eastern end of Taipa island and is the only airport in Macau, which opened for commercial operations in November 1995. Since then, the airport has been a common transfer point for people traveling between mainland China and Taiwan, as well as a passenger hub for destinations in mainland China and Southeast Asia.
As in Hong Kong, Macau has its own immigration policies and is a separate customs territory from mainland China. All travellers, including those to mainland China, Hong Kong and Taiwan need to go through the immigration and customs inspections of international flights.
I went through this airport many times during my stay in Macau, and I must say, though small, it is very efficient and it has good facilities.
