Airlines are still recovering from the global tech outage. What are your rights if you’ve been stranded?

A faulty software update by CrowdStrike caused chaos this week as countless industries suddenly lost access to their technology systems, including many major airlines – and now travelers are wondering what their rights are after being stuck in airports for days.

While airlines are recovering, there have still been widespread issues. On Tuesday, there have been more than 700 cancelled flights into, out of, or within the US, while nearly 4,000 have been delayed. Delta Air Lines is among the worst impacted, making up the majority of cancellations and delays.

Delta is offering waivers to impacted customers, the Associated Press reports, but many across the country still find themselves stranded. The Hartsfield-Jackson Atlanta International Airport is the worst impacted, with more than 250 delays and nearly 100 cancellations on Tuesday.

This comes after some 5,500 flights were canceled and more than 22,000 were delayed across Sunday and Monday.

The headaches have left passengers wondering if they have any rights and recourse to deal with the situation. Here is a helpful guide to those rights:

Rebooking and accommodations

In the event of a “controllable” cancellation or delay, all major airlines say they will rebook passengers at no additional cost, according to the Department of Transportation. These major airlines include Alaska, Allegiant, American, Delta, Frontier, Hawaiian, JetBlue, Southwest, Spirit and United.

Passengers currently have the right to request a refund from an airline if their flight is canceled – because of the airline’s fault – and they choose not to rebook.

These major airlines also guarantee passengers a meal, cash for a meal or a meal voucher if their cancellation or delay forces them to wait more than three hours. With the exception of Frontier, these airlines will also provide complimentary transportation and lodging for overnight delays.

Passengers should always try to find out how long a delay will be and seek alternatives on other airlines, the DOT says.

“If you find a flight on another airline, ask the first airline if it will endorse your ticket to the new carrier; this could save you a fare collection,” the DOT writes….
