While the June 2022 Skyclub access change isn’t further helped with current delta operational problem, I do believe more change is looming. I think the recent change did little to the crowding situation with further action necessary.
As for the American Express side of things, benefit guide of June 2022 access change also include the statement,
“Benefit and rules subject to change without notice”, with “Additional restrictions may apply.”
It is my belief that Amex and Delta is still coordinating their efforts to find the right solution to remedy this problem. it wouldn’t surprise me, visitation frequencies and/or booking class might indeed factor in to future language of access.
