What does it mean for airlines when faced with an "undue burden" claim?

When airlines face an "undue burden" claim, it indicates that they may encounter significant difficulties or expenses in complying with the requirements set forth by the Air Carrier Access Act. This term is essential in understanding the balance between ensuring accessibility for individuals with disabilities and recognizing the operational and financial limitations that airlines may experience.

The concept of "undue burden" refers to situations where compliance would impose substantial difficulty or costly challenges that could negatively impact the airline's ability to operate effectively. In such cases, airlines are expected to demonstrate that the burdens they face are significant enough to warrant a deviation from certain compliance requirements. This doesn't mean they can simply disregard the rules; rather, they must provide compelling evidence of the challenges they face.

By acknowledging the potential for undue burden, the law allows airlines to navigate the complexities of providing reasonable accommodations while considering the practical realities of their operations. It ensures that airlines are not held to an impossible standard, while still encouraging them to work towards greater accessibility for all passengers.
