Thanks,
I understand that, but since I am using ANA miles I am trying to minimize the fees they pass on, so I am trying to use a US carrier TATL and am wondering which one is best between CO, US and UA for Business class.
I am hoping this way the taxes will be much lower than all 4 legs on LH or LX etc... or they might even price the whole itin out as a CO or US itin (that is how it prices out whet I tried a paid booking using CO TATL (1st and last legs, EWR-FRA and FRA-EWR) and then LH FRA-TLV-FRA).
I will call them up to price it but was hoping for input on US carriers for these legs. There are no available direct flights in business for my dates (Lag Bomer) and am considering direct in Economy or with a stop in Business.
