Hi,
I am a frequent flyer in British Airways, been travelling with them for years but I've never been taking care of my miles until now. I am about to change from one level to another, but my membership renews in October.... so I understand I have to travel and change tier levels before October. I think it happened to me last year that I accumulated all the miles to go to Bronze but the flights didn't fall before October so I went back to zero tier points...

1. I am travelling with my sister soon and I wanted to know if it's possible to book her tickets with my frequent flyer number so that I can get the tier points generated by her flights. Is that possible?

2. Do you know if the miles also get reset ? and I should spend them before October too?

Hope you are able to help me with my questions, thank you very much!
