Yes, airport lounges can absolutely be "pre-booked," and in 2026, it is highly recommended to do so due to increased crowding. Many independent lounges, such as those in the Plaza Premium or No1 Lounges networks, allow you to reserve a specific time slot directly on their websites or via apps like LoungeBuddy or Priority Pass. Pre-booking often costs between $30 and $60 and guarantees you a seat, which is crucial during peak holiday periods when "walk-in" guests are frequently turned away. Some airline-specific lounges also allow "One-Day Passes" to be purchased through the airline's mobile app, though these are often "space-available." If you are a member of a program like DragonPass, you can often "pre-register" your visit for a small fee to secure entry. Booking in advance not only ensures access but often includes a specific "window" of time (usually 3 hours) and sometimes allows you to pre-order premium services like a shower or a spa treatment.
