To secure an earlier boarding group on United Airlines in 2026, you generally need to hold elite status, a specific credit card, or a premium cabin ticket. Group 1 is reserved for Premier Platinum/Gold members and those in First, Business, or Polaris cabins. Group 2, which is the most accessible "early" group for many, is granted to United Credit Cardholders (such as the Explorer or Quest cards) and those who purchase "Priority Boarding" or "Premier Access" as an add-on during checkout. If you don't have these, your group (3 through 5) is determined by your seat location: window seats board in Group 3, middle seats in Group 4, and aisle seats in Group 5. Therefore, choosing a window seat is a "free" way to board earlier than those in aisle seats. For those with special needs, United offers "Pre-boarding" for customers with disabilities, active military, unaccompanied minors, and families traveling with children age 2 and under, regardless of their ticket type or seat location.
