I'll concede that American Airlines could have treated its customers with more courtesy, offering them food and drink. It's certainly possible that American could have performed better maintenance on their planes. But it's good to know that their pilots are safe, and won't risk flying over the ocean if they have a slight (realistically irrelevant, given GPS) instrument issue.
Agreed that the pilots did the right thing, but the customer facing staff did not.
I think the question here is is this an institutional problem with AA, or a one off. From everything I can seen, and my own experiences flying in the US, this seems to be a regular issue for AA and other US airlines.
(I judge the necessary amount of compensation from the statements that they turned 'halfway across the Atlamtic' and landed 'heavy'. I do not think both can be true.)
I am curious about your choice of the word "intentionally".
Do you think that some person or persons decided to make travelers miserable on purpose e.g. because they are stuck at work and are bored?
(Yeah, yeah, don't put on your clever pants, I know where limbo is!)
