Hi

We have a ticket on LAN, and one segment is SCL to GRU, originally booked on N booking class. Following a schedule change by LAN, we called up AA.com (where we booked the ticket from), and moved to a later flight. In the process, the booking class of the segment has become T. Checking on both AA and BA - T class doesn't seem to be listed as a miles earning class? Does anyone know what T class is used for in LAN?

Thanks
