JetBlue did not respond to requests for comment but told The Wall Street Journal it expected to retrofit 17 smaller Airbus jets by October, with possible “limited impact” some days in Boston. The airline's Boeing jets have upgraded altimeters, as do all Delta Connection planes, which are operated by Endeavor Air, Republic Airways and SkyWest Airlines, according to the airline. The Delta planes that have not been retrofitted include several models of Airbus jets: all of its A220s, most of its A319s and A320s and some of its A321s. None of them were tied to 5G issues, according to the airline. FlightAware listed nine Delta flight cancellations Saturday. The airline plans to route the 190 planes carefully to limit the risk of canceling flights or forcing planes to divert away from airports where visibility is low because of fog or low clouds. The airline does not expect to cancel any flights because of the issue, Delta said Friday. Delta says it has 190 planes, including most of its smaller ones, that still lack upgraded altimeters because its supplier has been unable to provide them fast enough. American, Southwest, Alaska, Frontier and United say all of their planes have height-measuring devices, called radio altimeters, that are protected against 5G interference. airlines had made the changes needed to adapt to 5G. But Arrndt also stressed that the Federal Aviation Administration is “working very closely with airlines to monitor summer pop-up storms, wildfire smoke, and any 5G issues.” Transportation Secretary Pete Buttigieg recently told airlines that flights could be disrupted because a small portion of the nation’s fleet has not been upgraded to protect against radio interference.īut the worst fears about 5G hadn't cropped up by mid-afternoon Saturday, prompting Transportation Department spokesperson Kerry Arndt to describe flight travel as being at “near-normal” levels. The leader of the nation's largest pilots' union said crews will be able to handle the impact of 5G, but he criticized the way the wireless licenses were granted, saying it had added unnecessary risk to aviation. They then agreed to limit the power of the signals around busy airports, giving airlines an extra year to upgrade their planes. Predictions that interference would cause massive flight groundings failed to come true last year, when telecom companies began rolling out the new service. Heading into Saturday, one of the biggest concerns had been whether 5G signals would interfere with aircraft equipment, especially devices using radio waves to measure distance above the ground that are critical when planes land in low visibility. Federal Aviation Administration also advised travelers that bad weather conditions on the East Coast could affect flights later Saturday.
