A new Department of Transportation (DOT) rule, which went into effect last month, could make it harder for some travelers to receive compensation for certain flight disruptions.

The rule has received renewed attention following a nationwide Federal Aviation Administration (FAA) ground stop on Friday, which has left travelers waiting aboard planes, unsure how long they will be stuck before taking off or returning to the gate.

What we know: Effective Oct. 19, the DOT removed ten events which cause flight disruptions from being considered "within an airline's control," removing the ability for flyers to get compensated.
