To make a connecting flight: 90-120 minsSince Singapore is a city-state, any connection through SIN will be international. To be on the safe side, budget at least 1.5 hours to make your connection if you only have carry-ons and/or your bags have already been checked through to your final destination.
What is a good connection time? Travel advisers say there's a lot to take into account when booking connecting flights, but a general rule of thumb is 60-90 minutes between domestic flights and at least two to three hours for international itineraries.
Transit Shuttle Bus ServicesThe estimated time taken to travel between the terminals using the transit shuttle bus is as follows: T4 to T1: 18mins. T1 to T3: 6mins. T3 to T4: 12mins.
By Skytrain: Access Terminal 2 by free Skytrain service, which operates from 5am to 2.30am, at both the transit and public areas. By Foot: Access T2 via Changi Airport's Mezzanine Level link bridge above the MRT station. It takes approximately five minutes to walk between T2 and T3.
WITHOUT ONWARD FLIGHT BOARDING PASSFollow the directional signs to get to the boarding gates. Note that passengers are required to go through security screening before heading to the boarding gate of their onward flight.
For international layover flights booked on one airline, two hours is often recommended to make your connection. For international flights on different airlines, the connection time will need to be even greater as you may have to change terminals between the two flights.
If you've missed a connecting flight due to circumstances beyond your control, such as heavy air traffic or bad weather, and you're flying with a major carrier like Singapore Airlines or Qatar Airways, you can expect to be issued a brand new boarding pass and booked on the next available flight for no fee.
Check in your bag before your first flight. The airline will take care of the rest. In most cases, you won't have to collect and recheck your bag between flights.
You'll need to clear customs and immigration. Next, you'll recheck your luggage for the domestic flight. Finally, you'll need to go through Transportation Security Administration screening. This may include a physical inspection of your luggage and personal items with a metal detector or a full-body scan.
So how do you know how much time to leave for connecting flights when you have booked with two separate airlines? The rule of thumb is that you leave AT LEAST 3 hours from arrival to departure for international flights and 1.5 hours for domestic.
What is the recommended layover time for international flights? International flights require longer connections as you will often have to go through immigration and customs upon arrival. For international layover flights booked on one airline, two hours is often recommended to make your connection.
