That's a difficult question because prices for flights depend so much on the season during which you travel. Even the days of the week that you book on and/or travel on can make a $100 worth of difference in prices. From San Francisco to Bali it looks like Singapore Airlines offers the least expensive flights for about $1000. about 7 years ago
Bali is nowhere near Orlando or London???
Try searching the airlines that fly that route and then go from there. There are a few discount airfare websites you can search on. Here are 2 that I use regularly.
