last week I purchased a round trip LAX-TLV for Jan. 2012 in WT+ and MFU'd to CW and now I stumble across this NA fare sale
It turns out I am paying about $1k more than at the current price offer. I have tried to see if I can cancel but I guess once you MFU the tix becomes highly restricted and if I were to cancel I would only get taxes and surcharges back. If I only waited!!
