On a OW award ticket in South America, was scheduled to fly GIG-SCL-LIM on LAN751 and LAN632. Flight 751 makes a stop in GRU with 50 minutes on ground, but not visible in itinerary.

After takeoff from Rio, electrical system in cabin has cascading failures, first entertainment units and seat lighting, later seat motor controls so some landed with legrests up and backs reclined, even had some signs like Lav light flickering and going off. On ground in GRU, pilot announces that due to technical issues we need to deplane. About 2.5 hours later, the flight is cancelled.

Many rerouted on later GRU-SCL flight, but our last connection to LIM would not be possible, so LAN agent moves us to a GRU-LIM nonstop. We ended up with an early arrival because we cut out the indirect leg through SCL. All seemed good.

However, LAN did not record us as having taken the LAN751 nor the LAN632 flights, instead seeing us pop up wiht a GRU-LIM flight. To them, we stuck in another open jaw and rerouted without working with them, since the GRU stop is hidden in the LAN751 flight routing and not visible. They unilaterally and without contacting me cancelled all the following segments.

I just happened to spot this by seeing that the flights were still listed on the AA.com website, from whom I booked the award, but the seat assignments went away. I checked on LAN.com and all were gone.

I am in Lima, due to fly to Cusco tomorrow on a nonexistent reservation, then home on 7/1 from CUZ-LIM-LAX-SFO with the CUZ-LIM-LAX part now cancelled.

The agent to whom I spoke now understands what happened and that it was not my instigation, instead an involuntary reroute by LAN, but I am on tenterhooks while they "request reinstatement" of the segments and promise to call me at some point to let me know when it is successful.

If I had not idly checked, I would have been at the airport tomorrow and very probably unable to get it all sorted out in time to fly to Cusco. At this point, I have been waiting hours and so far no segments added back. Most likely it will not happen until the staff come to work tomorrow, yet I would need to leave my hotel by about 11AM to make the flight assuming they rebook it.

If you have any anomalies in your award flights, check and double check.
