MLOS

MLOS (Minimum Length of Stay) is a revenue-management restriction that requires a booking to span at least N nights to be confirmed. It is used during high-demand windows to protect inventory for higher-value multi-night bookings instead of single-night flips. MLOS is the most commonly used length-of-stay control, paired with CTA (Closed to Arrival) and CTD (Closed to Departure) for finer-grained inventory protection.
