Just wondering if anyone can help with information on transit at Changi. Arriving on BA11 at 15:05 departing 18:35 to Bali on Jetstar. Both use Terminal 1.

I assumed we would have to clear immigration, collect bags, then drop bags at Jetstar desk and go out through immigration again(fills up the passport!)

But found a Changi website that suggests otherwise. Anyone have the facts?
