Aeromexico — stress, trouble, and waste of time

Yesterday, my mother had a Aeromexico 4:40 PM flight from Guadalajara to L.A. I'm sure since the flight less than capacity given that this isn't the busiest time of year, Aeromexico cancelled the flight and put her and everyone else that had that flight onto their next one, which was 5 hours later. This shows the airline puts no value on a customer’s time. All they offered was a meal voucher. They wouldn't even offer to put her on the next flight out to L.A. on Mexicana, Delta, or any other airline. People were outraged, but Aeromexico personnel did not care. When her plane finally arrived in L.A., instead of arriving at the Delta terminal as is the procedure for Aeromexico flight out of/into L.A., they were bused to the international terminal - after they waited almost an hour at the gate for whatever reason and passengers wouldn't even be given a chance to call family members on their cell phones to let them know of the additional delay and of the terminal change. Passengers, especially the ones that had the original 4:40 flight like my mother were incensed at the whole experience. Many people, including my mom, stated that they would write complaints to the airline, but I’m not holding my breath as to any compensation for the stress, trouble, and waste of time caused.
