How long are Business Rewards Award tickets valid for?

Business Rewards Flex Award tickets are valid for one year from the date of issue, and Business Rewards Saver Award tickets are valid for three months from the date of issue.

Why should I buy a Skywards Flex fare when a cheaper Skywards Saver fare is available?

Do I earn the same Miles Accelerator bonus if I have purchased a Skywards Flex or Skywards Saver fare?

Can I combine Saver rewards and Flex rewards?
