It is interesting because at the moment not all *A carriers are E-tix capable. If I throw in a sector on TG (for example), I will not be able to get E-tix. Then what if I redo the routing in the middle of the trip? Would it be as easy as paper tix to deal with? I am assuming if once I exchange this E-tix to paper tix because of TG in my itinerary, the next rerouting will still be on paper tix, even if the rest of the segments are on SQ only for example.

When you reach higher status of UA MP than when you book the flights originally, your new status will not be reflected in your booking, unless you call UA to reenter your MP#. But on SQ, when you qualify for PPS, the PNR will get updated right away showing your new QPP status.

t1nt1n, you said F2? I guess you did not plug my routings in the great circle map...
