Hi all

I am flying to Singapore with emirates and then onto Bali with Garuda Indonesia on a separate ticket. I have a two hour turnaround. I have called emirates and they cannot confirm that they will through check my bags for me. My questions are:

1. Has anyone known emirates to through check bags to Garuda?
2. Can this be dealt with airside in Singapore?
3. If I have to leave airside and exit immigration etc, is 2 hours enough time to pick my bags up and change terminals ?
