So I flew back to Hong Kong today on CX 889 from Vancouver. Upon check-in, the agent realized that my birthday (May 18) is on the day of arrival and she quickly offered me the upgrade (J to F) to "help me celebrate my birthday"! Then, the ground staff sang me the song...

Just before the plane landed, the flight attendants also came over to give me a cake (with candle of course), a card signed by the cabin crew and sang again...

This is definitely the perfect way to start the year! Perhaps I should fly on my birthday every year now just experience this!
