Hi guys

A girl at work is off to LAS to get married.

They bought ultra cheap flights on UA - in the recent fare deals, and I said to her she should make sure she gets some points for it.

She is originally from GIS and often travels SYD AKL.

So what is the better option.

Sign up with United or Airpoints?

I'm not using Airpoints at this stage so not familiar enough to give her the best advice.

Thanks

Adam
