“Based on customer feedback, we made several policy changes to help ensure that the exceptional experience is reserved for Delta Sky Club members and their guests who choose to fly with us,” Delta said in a written statement.
Sky Club members also won’t have access to Air France, KLM Crown or Virgin Australia partner lounges, unless they have “elite plus” status.
Another move that limits who can get into Sky Clubs is Delta’s move in November 2018 to discontinue Sky Club day passes. The airline previously sold day passes for $59.
There are separate restrictions for those who have Delta Reserve, Platinum or Centurion American Express cards to access Sky Clubs.
