It is a neat concept, however be careful.
I purchased back in July a bunch of stuff and points were always pending. On their site was told points will be credited within 30-60 days and now 60 days has past and not credited.
I reach out to support and they said it could take another 4-8 weeks for them to investigate.
So they are promising miles but they are stuck in pending status and I have not been able to redeem them.
Has anyone here received and were able to book with their miles?
