Do you want to know what occurs when a flight from Qatar is delayed? There are many different things that can cause a flight to be delayed, including bad weather, medical problems, technical difficulties with the aircraft, etc. Every Qatar flight that departs for or arrives from the US is required by US law to offer passengers a Qatar Flight Delayed Compensation to make up for their inconvenience. Other airlines that arrive at or depart from the US must likewise abide by this law. The flight's delay must be at least three hours long to qualify for this reimbursement. The airlines are not responsible for making up for events that are outside their control.
