Lawsuits filed demanding refunds for flights the airlines canceled because of the COVID-19 pandemic have barely gotten off the ground, with at least two dismissed by federal judges so far.

Major airlines, both domestic and international, face more than two dozen class actions, most asserting breach-of-contract claims. But, in the past month, federal judges in California have dismissed cases against Norwegian Air Shuttle and Deutsche Lufthansa after concluding that the plaintiffs did get refunds—just not as soon as the seven days required by U.S. Department of Transportation notices in April and May.
