I got an email from them yesterday which said they will be flying into Honolulu at least, later this year. Keep a good eye on it because they usually do exceptionally cheap promo flights when starting up a major new route.At the moment it's just a twinkle in my eye but I have California on my list of future zoo-trip destinations. AirAsia is going to start offering a budget long-haul flight to undisclosed destinations in the US, and hard to imagine there won't be a KL-LA route.
I'm not sure I'm that keen on going anywhere near the USA for the next, let's say, four years.
They are also talking about restarting the KL to London route (which they stopped in 2012).
