Might have been a real app once, has been taken over by ads – Travel Hacking Review

The "links" they refer to are enticing enough-secrets from flight attendants on getting upgrades, getting the cheapest seats, etc. but the links lead you to totally unrelated sites that have nothing to do with travel--just Junk and perhaps, viruses. Why Apple has allowed this to continue this ruse, I don't know.
