- For the best Changi Airport experience, if you have a 5+ hour layover, book the free Singapore Tour (available multiple times daily) – it shows you Marina Bay and the city in 2.5 hours.
- Book connecting flights with at least 2.5 hours layover at hub airports (Dubai, Doha, Istanbul) to allow for security re-clearing. Emirates and Qatar have excellent transit facilities if delays occur.
