I emailed Singapore Air yesterday to ask about sales to Bali and this was the response:
"Thank you for your email regarding flights to Bali. Currently we do not have any special airfares to Bali, these are not likely to be released within the next month or so as the current selling season is UK/Europe. We cannot advise a definitive date as to when specials will be released, but when they are released there will be extensive media advertising, you may also periodically check the website www.singaporeair.com for updates"
Goodness knows why they can't have more than one region having a 'selling season' at the same time? but I guess I will just have to be patient and wait a little longer ...
