I don't see any way to correlate these fares to the UA chart without issues (e.g., L seems like a cheaper fare on the UA chart than M, which does not seem to be the case in Avianca world). Any *A veterans willing to help? I searched the forum and couldn't find an answer.
Can you find the routing via ITA Matrix? There are still the underlying fare classes, they just aren't visible to you. For example, randomly picking some parameters, I can find Avianca booking into S, Z, P, E, V, Q, L, M, etc...
