FC food on US is variable. Longer flights (except Hawaii which has terrible food and FC seats) tend to be better, but not as good as a flight to europe. Its as though they figure that people going on vacation like to eat badly. CLT-AUS suffers from this, but not as badly as HI flights.

Domestic FC food can be OK eg the manicotti/tortellini, or like prison food eg the new braised beef about which nothing good can be said.
