Wouldn't you at least consider this a useful use case: Purchase a flight online on a website, but then get a push notification if there is a flight change? Why should we force a user to download an app to support that use case.
Why not just use SMS instead? It's timely, and it works even if the target device is in an overcrowded airport and can't get mobile data.
For privacy reasons, some users would prefer not to give phone numbers. From a provider perspective, sms would become a significant cost if you're sending millions of texts, while push is essentially free.
