Issuing airline is UL, 603..... although the 1st 4 flights are on BA. I intend to fly the 1st 3 BA flights, then redo the whole ticket. I guess that I will have to deal with UL, but may pay a fee for the issuing TA to do all of the work. 1st flight is next year. Anyone changed their ex-SEZ ticket after flying 1st segment? My copy of the rules from EF stated 2 entries into N America is OK, no need for 1 to be a transit w/o stopover.
