i see no logical relevance in your example.

a more accurate use of your hypothetical: in your example, if i oversleep the flight (as opposed to it being canceled), AA could possibly charge me hundreds and hundreds of dollars (a lot more than your $150) or preclude me from flying altogether depending on availability.

in that situation, it is my fault, and i am forced to take responsibility. if i have irregular ops, i can assure that AA doesn't care.
