I admit I don't fly Coach often, but when I have as a United 1K, the flight attendant often comes down the aisle with a slip of paper, checks my seat number and asks if I'm Mr. Love and hands me a free headset cord. Also on the slip of paper are the names of any United employees onboard. They also comp my drinks. If they don't do the list thing, when I hand them my special 1K drink/headset coupon they hand it back, and comp everything. I asked about this unwritten "perk" and was advised that it was the Purser's choice if they did this or not, so this is a bit spotty if you get it or not. But as Rudi said, they send 1K's a bunch of coupons anyway, so in effect they are free for 1K's.
