For shorter connections, you can explore indoor gardens, themed rest areas, play areas, and a wide selection of dining and shopping options without leaving the transit area. If you have a longer layover and sufficient time, Changi offers leisure facilities, quiet zones, and transit hotels so you can rest between flights.
