Yes, you can generally give a United Club one-time pass to a friend, provided it is a digital or paper pass not tied specifically to your name or membership card. If you earned the passes through a credit card like the United Explorer, they are usually "transferable" in the sense that anyone holding the QR code can use them. However, there are strict admittance rules in 2026: the person using the pass must have a same-day boarding pass for travel on United, a Star Alliance partner, or a contracted partner flight. They cannot use it if they are flying on a completely unrelated airline like Delta or American. Additionally, the friend must be at least 18 years old to enter alone. If you have a full United Club Membership, that is non-transferable and cannot be loaned to anyone else; you must be present as the primary member for any guests to enter with you.
