Hi, I'm a little confused about what happens to luggage within the transit lounges/hotels at Singapore airport. We arrive into Singapore on SIN at midnight & plan to stay in either the Transit Hotel or lounge. Our flight out is with SIN and departs at approx 9.30am. In the past we have checked our luggage through from destination to arrival as we are using the same airline, is this possible with such a long lay over? Or does our luggage go to "lost & found"??
