This is probably the wrong forum. Feel free to move.
I enter the SkyClub with my Amex Platinum and used to pay for my guest with either the Platinum or Hilton Aspire. On this past trip, they wouldn't allow me to pay for the guest with my Aspire.
On the rules page it states that members who have access with a Reserve or Delta Platinum must pay for the guest with those respective cards. It doesn't say that under members who enter with a Centurion or Amex Platinum.
So can I technically pay for a guest with the Hilton Aspire or not? I asked three different people at the SLC Club and they all said it had to be the same card, but that isn't what the small print says.
