Whether the fare will be standard or flex seems to depend on the fare bucket itself. I have validated the mapping below on a few routes but at this point it wouldnt surprise me if there is more variation.
Has anyone figured out what the various ex-US TATL fares map to? Trying to figure out if an ex-US UL206NCV (SFO to DUB), and MLX00INC (DUB to YYZ) are both high flex class (basically just want to confirm that it's 15 and 11 eUpgrades respectively, and ideally how the fare may map in eUpgrade priority (inferred fare brand).
