The U.S. Department of Transportation (DOT) today fined United Airlines $20,000 for providing inaccurate information to passengers about how much compensation they could potentially receive for lost, damaged or delayed baggage on international flights.
They have be more responsible for that. They should delivery the bags at the baggage claim and no more wait for 15 minutes.
