The latest info on Philippine Airlines mobile apps
As the most popular mobile platform in the world, Philippine Airlines has taken notice of Android and provided an app for most Android devices. With their Android apps you can search for flights, view existing reservations, or go paperless and use your mobile boarding pass via the app or Android Wallet.
