Guys, let me be more specific.

I fly like 10 times a year
TelAviv-SouthAmerica.
My company will pay only economy, and
as you could suspect, I live in airports waiting for connections, so free lounge access is the most important.

I have AAdvantage Gold, and I've already
contacted UA, and they are willing to give
me 1K. I contacted also Lufthansa, but still
no reply from them.

I don't know. I'm inclined to Lufthansa.
What would you do?

Thanks
