Expert Tips for Maximizing Chicago ORD Lounge Access
- 💡The United Polaris Lounge (T1) is strictly for long-haul business class. Star Alliance Gold/Domestic First do NOT get access.
- 💡Terminal 5 is NOT connected airside to T1/2/3. You must take the train (ATS) and reclear security.
- 💡Priority Pass options are very limited. The Swissport Lounge in T5 is the main option and often restricts access due to crowding.
- 💡If flying United Domestic with Star Alliance Gold, use the United Clubs, not Polaris.
- 💡Allow extra time for Terminal 5 security, as it handles all international volume.
Timing Strategy: Peak lounge demand at Chicago O'Hare typically occurs during evening transatlantic departure banks (5 PM - 11 PM) and early morning waves. Consider scheduling connections during off-peak hours when possible to maximize amenity availability.
