As part of its monthly Air Travel Consumer Report — which also includes data about flight cancellations, mishandled baggage and on-time delays — the DOT said it was releasing the data on reports of airline discrimination as concerns rise about the treatment of passengers. The data includes complaints of treatment based on ancestry, color, national origin, race, religion and sex.
The DOT found that there were 67 complaints from January to September this year, up from 49 complaints for the same period last year — a rise of 37 percent.
For the first nine months of this year, there were 52 complaints regarding race, eight regarding national origin, four regarding sex, two regarding religion and one regarding color.
Six of those complaints were received in September: three regarding race, two regarding national origin and one regarding religion. This is down from eight in September 2015 and 15 in August of this year.
The DOT investigates all allegations of discrimination against airlines to see if a violation has occurred.
