How to book a T class fare on NW ?
I've found on ITA a T Class fare for a travel ORD-MSP-MEM-LAS-MSP-DTW-ORD.
I've checked with KVS that all flights have T class seat available, but when I try to book this travel, either I can't find the fare, or when I've found it (on orbitz), the price changes when I intend to buy it.
Does anybody have an idea about ?
