This will be handy if you're using Google Now, which is Google's context-aware service that gives you information when and where you need it based on information you give Google.
The service is available on Android and iOS.
PREEMPTIVE STRIKE: Some of you may find this creepy but it is an opt-in service, with different levels of granularity.

This means that when you make a booking through www.singaporeair.com and send the results to your Gmail, you'll be able to get flight information like your schedule, airport terminal and departure gate information in Google Now automatically before you fly.
