Did you request a refund for a canceled flight or mishandled baggage, only for Deutsche Lufthansa AG to deny it, offer a useless voucher, or ignore you entirely? Don't waste another minute on hold.

Filing a formal DOT complaint bypasses standard customer service and forces the airline's executive team to respond to you within 30 days to avoid federal fines.

But the airline industry in the US is heavily regulated by the Department of Transportation (DOT).
When you file a formal complaint with the DOT, it doesn't go to a standard call center. The DOT requires airlines to acknowledge receipt of the complaint within 30 days and provide a substantive response to both you and the DOT within 60 days. Because airlines can face massive civil penalties for violating consumer protection rules, these complaints are handled by highly trained executive or legal teams who actually have the power to issue your refund.

Lufthansa is Germany's flag carrier, headquartered in Cologne, with major hubs in Frankfurt and Munich. On U.S.-departing flights, passengers are covered by DOT refund and denied boarding rules, while the Montreal Convention applies to international baggage claims. On flights originating in the EU, passengers may separately be entitled to compensation of €250 to €600 under EU Regulation 261/2004 for delays of three or more hours or short-notice cancellations caused by the airline. If Lufthansa does not resolve a complaint, U.S. travelers can escalate to the DOT.
