Airline passengers who have endured tens of thousands of weather-related flight delays this week got a welcome respite from the headaches Saturday, despite concerns about possible disruptions being caused by new wireless 5G systems rolling out near major airports. Data compiled by tracking service FlightAware shows the number of flight delays and cancellations have declined from the spikes recorded earlier in the week. Another tracking service shows the cancellation rate works out to about 1% in the U.S. as of Saturday afternoon. A spokesperson from the U.S. Transportation Department says flight travel has returned to “near-normal” levels.
