I actually think Star Alliance benefits could use some improving. I hope it's on-topic enough for this thread.

For my domestic US flights, I really don't care what airline I'm on, and almost always choose based on price. For the few flights in this category, the miles I lose out by flying DL or AA don't offset several hundred dollars in difference. And if I happen to be in Y, the only benefit I get on UA is lounge access.

I'd like to see a level above *G that includes things like free preferred seats alliance-wide. That would actually encourage me to book UA if I'm flying in Y.

Then you could throw in other things like F lounge access or whatever.

But as it stands right now, I have no reason to book a flight on UA if DL is $50 cheaper or 1 hour more convenient.
