Brussels Airlines is Belgium’s largest carrier, routinely transporting over 10 million passengers every year. With so many passengers and moving parts, there are bound to be some shortcomings that require official Brussels Airlines complaints.

Most commonly, passengers complain about Brussels Airlines flight disruptions and luggage issues, but there are other worthwhile reasons to file complaints. We’ll detail your individual passenger rights, the best procedures, ideal contact methods, and even how AirAdvisor can help you resolve the situation.

What Types Of Brussels Airlines Complaints Are Common?

Many of the common Brussels Airlines complaints are worthwhile because they trigger compensation from the airline, up to €600 in fact. Here are a few examples:

• Delayed flights - must be delayed by a minimum of 3 hours.
• Cancelled flights - must be cancelled with a notice period of fewer than 14 days.
• Denied boarding - applies when Brussels Airlines bumps you from a flight for which you have a ticket and have not agreed to give up your seat.
• Mishandled luggage - applies when the airline damages, delays, or loses your bags, and compensation can be up to €1300.
• Feedback on the passenger experience - recommended when you receive poor service, which may result in Brussels Airlines issuing coupons or discount vouchers.

Brussels Airlines Passengers’ Rights

Since this carrier is EU-based, it’s required to adhere to the provisions in Regulation EU 261. This is specifically what requires Brussels Airlines to compensate customers for flight interruption issues. For example, as long as your flight encounters a delay at the final destination totalling 3 hours or more, you should file a Brussels Airlines complaint for the following:

Additionally, your Brussels Airlines flight must depart from or arrive at an EU airport or be entirely within the EU to qualify. Flights that originate outside the EU that fly to destinations outside the EU are exempt.

For luggage problems, the Montreal Convention specifies the compensation amounts that are necessary when you submit Brussels Airlines complaints regarding mishandled bags.
