Does this language in Amex Reserve CC Terms and Conditions mean that Guest Passes are not usable within any 24-hour period until after January 31, 2025?
It seems to me that the "Effective February 1, 2025" language refers to pass expiration and the definition of a "single visit" "Lounge Agents say the opposite -- literally one single entry."Effective February 1, 2025: Delta SkyMiles® Reserve Basic Card Members will be issued four One-Time Guest Passes for complimentary access to the Delta Sky Club or usage of the Delta Sky Club "Grab and Go" feature within 6 to 8 weeks after Account opening, and thereafter every subsequent year within 6 to 8 weeks after February 1 while the Account is open. Additional Card Members are not eligible. One-Time Guest Passes will be available to view in the Card Member's Wallet in the Fly Delta app and in My Profile on delta.com under Certificates, eCredits, and Vouchers, typically within 1 week but in some instances, the deposit could take up to 8 weeks (for example, when the name on your SkyMiles account doesn't match the name on your Amex account). One-Time Guest Passes issued from February 1, 2025 through January 31, 2026 will expire on January 31, 2026, and One-Time Guest Passes issued in subsequent years will expire on January 31 of each calendar year thereafter.

Redeeming a "Delta Sky Club One-Time Guest Pass" will enable access to one or more Delta Sky Clubs or usage of the Delta Sky Club "Grab and Go" feature, at one or more airports, for a period of up to 24 hours starting upon the first Delta Sky Club entry or Grab and Go usage, during the guest's travel on a same-day Delta-marketed or Delta-operated flight. A single One-Time Guest Pass will permit usage of Delta Sky Club(s) in multiple airports during the 24-hour period. For example, if you visit a Delta Sky Club in different airports on a trip, entry into one or more of these Clubs will be considered part of the same visit as long as these additional entries occur within 24 hours of the first Delta Sky Club entry. If travel exceeds 24 hours from the first Delta Sky Club, then a second Guest Pass will be deducted if entering the Delta Sky Club or using Grab and Go more than 24 hours after the first entry."
