I feel like an intruder here because I'm an AC Super Elite, but my sister has put me in a place where I need to seek your help.

She has been an infrequent traveller on BA ex-YVR. Today she told me that her miles will expire in May because she hasn't added any points to her BA account in almost 3 years. Her intention is to stay with BA and oneworld, and will probably be travelling a lot more as her circumstances have greatly improved recently. She will be going to ABZ in June, but she believes that this is too late.

Can anyone tell me if she can save her points by doing a non-air transaction which gives BA awards, like a hotel stay? And perhaps a place that I can look to verify the rule?

Thank you for any help.
