What may occur if a passenger is refused transportation?

When a passenger is refused transportation, the procedure often involves rebooking them on a different flight as part of the airline's obligation to assist affected travelers. This action aligns with customer service policies that airlines follow to ensure that passengers are accommodated whenever possible, even if they cannot travel on their originally scheduled flight. Rebooking helps maintain a positive customer experience despite the inconvenience of being denied travel.

Other options, while they may be situations that can arise under certain conditions, do not directly represent the standard procedure followed by airlines. For instance, immediate refunds or filing complaints are not guaranteed outcomes; rather, they might require additional processes to be fulfilled. Similarly, suing for damages is a legal recourse that may be pursued in some cases, but it is not a standard or immediate consequence of being refused transportation. Therefore, rebooking is the primary and most common response to ensure the passenger still receives a travel opportunity.
