Without wishing to sound too pro-BA, BA is a public limited company, with a primary objective of providing returns to it's shareholders. So making a profit isn't necessarily a bad thing. And as a shareholder, I rather like the idea of some return on my investment.....

Also, the information is readily available via other sources (BA info line, BAA, BA.com etc). What you're paying for is the convenience of them telling you about it, rather than having to go off hunting for it yourself. I use similar services for sports results, the benefit being that I get the information on a timely basis instead of waiting until I read a newspaper, can go-online, or have a drunken mate phone me (though the concept of paying to find out that Scotland have lost at rugby yet again is somewhat masochistic... ).

At the end of the day, I guess it comes down to what you're willing to pay for information. Additionally, it looks like they've outsourced this to OAG, so they'll have their cut too.
