However you may find some trouble finding availability, specially in less than 6 months of anticipation. The rates are according to the new bilateral agreement between LATAM and each airlines.
You may found lack of availability since you can only book if the T class is open. If you book with LATAM Airlines you can redeem miles as long as the cabin is not full, of course you are going to pay more if only higher booking classes for paid passengers are available.
