Five-star airlines Qatar and Singapore usually start their fares to Bali in the low-to-mid $1,000s, but right now you can book many of them from $604 round trip through April 2021. These flights all come with flexible booking policies as would be expected from the world's best airlines. Keep in mind that some of the dates from West Coast cities will have a feeder flight on Alaska Airlines, but will still have a Singapore Airlines flight number.
Pirate Tip: Qatar has a very generous flexible booking policy that even allows for changing the destination for travel through the end of 2020.
