The link in this thread is now broken. What is the best way these days to tell what fare class an Avianca flight is? The only way I can tell is on the return flight of a round trip, you can click on Super Promo/Econo/Flex/Business Promo and it gives a slew of fare classes, but doesn't tell you exactly which one your ticket is. For example, Super Promo = U/T/S. But which specific class among the three options U, T and S is not given. Is there anyway to tell the exact fare class before purchase?
