> The airline web site could then present things Google can't do. Like "hey, we see you haven't checked in yet" or "TSA wait times are longer than usual" or "We have a more-legroom seat upgrade if you want it".

If I'm a passenger, there's plenty of ways for airlines to notify me. If I'm searching for a flight status online, it's because I'm picking someone up. If I want more information, I'll click through. I don't see how either me or the airline are hurt.

Why is that even a problem for Wikipedia?
