Most airport lounges, particularly those accessible via Priority Pass or DragonPass, have a standard 3-hour time limit to manage capacity and ensure all guests have a place to sit. However, enforcement of this rule varies significantly. If the lounge is not crowded, staff often overlook the time limit, allowing you to stay until your flight departs. Conversely, in high-traffic hubs during peak hours, you may be politely asked to move along once your time is up. Some premium airline lounges (like those for First Class passengers) do not have strict time limits, and "sleep pods" or nap areas in certain mega-hubs allow for longer stays. If you have a long layover and your lounge has a strict 3-hour policy, you can sometimes "check out" and "check in" again if your membership allows for multiple visits, or you may be able to purchase an extension. It is always best to check the specific lounge's entry in your app before arrival to see their current policy and occupancy levels.
