I could have managed 28K RDMs for $225 had I redeemed 3 $25 e-certs - much less attractive to me.
interesting.. I guess it makes sense if you use them like that. Pity you couldn't buy 9 x $25 vouchers for 9K miles instead of 3x $75 vouchers for 15K ;-)
Do UA not let you combine multiple vouchers on a single ticket? Please excuse my ignorance, I'm relatively new to UA/MP.
