JetBlue Airways has been fined $2 million for operating 'chronically' delayed flights, with the Transportation Department blaming unrealistic scheduling. The fine relates to flights on four routes on the East Coast in 2022 and 2023. Half of the money collected will go to affected passengers. JetBlue says it has improved, but delays and cancellations are still common. Only three in five JetBlue flights arrive on time, the worst of any carrier in the US.
