His/her point I am sure, and 4 attempts proves it inarguably, that if the flights are available and bookable on LH and CO...US is crooked and unethical in not having them also available.
For those of us who have flown nearly all of the time for 30 years or more, availability filtering is the highest level of customer mistreatment and loss.
