Delta has increased the price of lounge passes from $50 to $59, but they’ve tucked in another change. Lounge passes are now good for only one visit — you can no longer buy a full day’s worth of visits for that price. So the real comparison is what a single visit pass used to cost, which a year ago was just $25 and then $29.
Oddly if this were about crowding they wouldn’t charge $59, they’d charge $60, since they would want the price to seem more expensive. It’s about maximizing revenue.
Not only does most of the world have better lounges, they don’t charge elites for access at all — and it’s purely an historical accident that lounges come with paid access in the U.S. to begin with.
