The website is acting up, but here is an update regarding Retroclaim.
You can retro-claim up to 90 days. Your all previous points will take up to 3 hours to reflect in the account. It will show some error or page will refresh automatically. Do not try to add the PNR again.
If you are using a Mobile App or Website, you get 150 bonus points for every trip(Single, Round Trip, Multicity), even with the same PNR.
