Your flight will arrive at Changi Terminal 1. There are excellent shopping, dining and entertainment options at Changi. There are areas which have movies, sports and other media programs being screened. There are many quiet areas with lounge chairs where you can snooze in. Security when you re-enter the boarding area is quick, efficient and not unpleasant. You can walk through all the terminals if you need to stretch your legs – just walk from terminal 1 to terminal 3 then catch the skytrain to terminal 2 and then resume the walk back to terminal 1.
