Recently I was flying SCL-EZE on LAN. Wonderful experience (i'm AA Plat, and they treat you REALLY well down here...5x better than American treats its own plats). Got put on an earlier flight (as I was to the aiport before Chilean standards) and got an very roomy bulkhead seat on the A340. When I get there , there's a woman with 8yr. old child asking if I would switch seats with her (center block aisle pretty close). I immediately said yes, as I didn't want her separated from her son. In some situations I'm willing to be very accomodating, as she was very nice about posing the question. (That and it was 1hr 40min flight).
