Changes

 If you arrive by flight to SIN, and plan to cross the border overland, make sure you made a fake return e-ticket from SIN (to anywhere). There is a high chance that they ask you for your return itinerary at the check-in counter of the departure airport. It's a new regulation in Singapore Customs. While in some cases if you explain you go overland they may let you in, they also can be annoying. While leaving CDG to SIN with Singapore Airlines they accepted my explanations, but when I left MEL to SIN with Jetstar they just didn't accept any explanation and I had to buy a ticket I would never use departing from SIN, at last minute leaving me no choice ([[User:toortoth|toortoth]]). So make a fake, with a frame from another airline (in case they want to check in their own system, but they never do, it would be too long to check itineraries of all passengers, especially calling other companies). Cheapest ticket out of the country is most likely the Singapore-Batam ferry, can be booked online on batamfast.com for SGD15. Officially suggested by Jetstar.
