DNB Aviation Abbreviation

Denied Boarding

Denied Boarding (DNB) in the aviation industry refers to the situation where a passenger is not allowed to board a flight despite having a valid ticket and arriving on time. This can occur due to overbooking, operational reasons, or security concerns. Airlines often have policies in place to compensate affected passengers, which may include rebooking on the next available flight, monetary compensation, or accommodation if necessary.

The practice of overbooking, while controversial, is a common strategy employed by airlines to maximize revenue, anticipating that some passengers will not show up for their flights. However, when more passengers arrive than there are seats available, the airline must deny boarding to some individuals. The criteria for selecting passengers to be denied boarding can vary but often include factors such as check-in time, fare class, and frequent flyer status. Regulations in many jurisdictions require airlines to seek volunteers willing to give up their seats in exchange for compensation before involuntarily denying boarding to passengers.
