Can we confirmed Economy Advantage and Waitlist Business Saver?

[joyceful]

Hi all,
Just wonder are we able to confirmed the Economy advantage and waitlist on Business Saver? Economy saver have all gone, and Business saver all under waitlist. Just though of if really can't get business saver at least still secure the economy, as travelling time is peak season. Business saver and economy advantage points not much different, that is why though of waitlist business saver.

Any advice will be appreciated.

Thanks.
