Came out of MEX on March 3...pleny of staff ....excellent transistion. My trip had 14 segments. When I was checking times for TPA /HNL segment it was NOT on the RESERVATION. I thought I had done the unimaginable of not including this in my confirmed itinerary. SO, I quickly got a 40,000 mile reward ticket to HNL. Never got a notice for checkin for other flight, so figured I made the mistake. Flew nicely on reward upgrade to IAH and on to HNL. MY HNL to GUM segment was still intact and I flew on to Guam...kicking myself all the way! TODAY I checked the PAST itinerary and found to my surprise that the missing segent was indeed on the itinerary! NOW WHAT? Why was last segment not canceled if I missed one segment? Can I get some compensation for this unusual situation.? Called 1K line and got same answer as ordinary phone line. WAIT 72 hours. I'm not in the mood to just say forget it. Confused in Guam.
