Today I receive my first RTW in form of E-TIX instead of paper tickets. :-: Well, it will be pretty challenging when rerouting needs to be done later.
My E-tix is issued by SQ. The airlines involved are SQ, LH, and UA. According to SQ, the E-tix is only capable of containing 16 segments total. More than 16 segments, including open-jaw, paper tickets are necessary.
