There is NO choice, Mr Robbie86.
SINGAPOE AIRLINES is the only way to go and DO
make sure you break the journey and spend some time at Changi Airport. It is THE great arial crossroads and you will be amazed.
Plane your journey to have at leat an 18/24 hour break (there is excellent cheap budget accomodation in the transit hotels airside in each terminal and with an onward boarding card you can exit immigration and go visit Singapore as well as exploring Changi.
You will never regret it!
