american air line sucks

I was travelling from dfw to chicago at 8.30
Am flight. Air lines cancel flight no reason given would not
Accomodate on non stop flight until evening when
i talk to superviser she told me theuy can refund money
think of it if you try to change flight they will
chsrge you 150 dollat plus difference if fair.
What about air lines when they cancel flight ir
put you on another flight rulrs should be same
passanger should be comensated.air line undustry is
inly in this country get by with thos kind of arrogance
do mot travel via american if you can....
