The MP page seems to address only RDM and lists things by fare classes that don't match TACA's fare classes, so I'm having trouble figuring out whether or not it would be worth booking a TACA premium fare that I'm considering.

TACA's lifemiles would give me 125%, but their program is nearly useless to me and I need to EQM. It's been a couple of years since I've flown them so I don't remember how it works, beyond seeing that they still don't have a way to put in yoru UA number on-line.

Any ideas?
