"if you booked on lan.com/latam.com your PNR is a Sabre PNR" - This isn't quite true.
If you book on Latam.com with the country indicator set to Brasil, you will get a Tam issued Amadeus PNR. eg. The last Latam ticket I booked was on the 2nd June & the PNR is 7XXXO4.
The worst thing about this is that if you need to speak to a call centre & get Latam staff located outside of Brasil, they can't call up the PNR that their own website issued! So make sure you keep you e-ticket number handy as depending on where you book, where you fly & where you call, it may be the only thing that allows the call centre staff to access your booking.
