Is it, though?

What's the difference, realistically, from having an OTP token in, say, Google's authenticator app, and the generator built into the United app? It'd still do the over-the-wire authentication, which is the important part.

What's the security advantage of flipping back and forth between the authenticator app and the United app at login?

Now --- in theory, SHOULD you be using an OTP token on the same physical device you're authenticating? Not really, no. But that's - in practicality - what happens.

So what's the advantage?
