How do I find financial information of companies located at Diosdado Macapagal International Airport, Php?

I'm doing research of financial data regarding companies located at Diosdado Macapagal International Airport, Philippines. I am having a hard time searching for data through the internet. I would like to find a site that would address my requirements.|||i doubt you will find a site dedicated to this exclusively. wikipedia is a good starting point for information about the philippine airport. it lists many airlines that fly to and from the airport and each one will have a website. any of these companies that are public generally disclose their financial information, which is generalliy available on yahoofinance or other finance sites. if you can't find it there, try bloomberg or reuters (these are paid services so you can try the local library or a friend in finance). not sure by your question if you mean the airline companies at the airport or the concession operators. most of the concession operators will probably be private. one other place is dun and bradstreet, they have company reports for many private companies (not sure if they have companies in the philippines or not) but most of these reports require a fee and only give basic information such as sales, employees etc. hope that helps!
