From Channel 7 news:
The statement adds, quote, "International Airport Alliance is committed and strongly believes in the Ambergris Caye Airport project for which it has diligently worked on for over 14 months, and wants to assure the Citizens of Belize that we remain fully confident and transparent that our Company will not only fulfill its professional obligations, but will also do it in a way that Belize will be proud of."

Nice words, but we note that International Airport Alliance is a company with a letterhead, but little else. There's no address or telephone number, and no website, plus no track record of development that we could find.
