跟进：全美航班扰动进入第三天，周日逾1,600个航班取消，达菲称周一才能完全恢复

美国航班扰动11月15日进入第三天。据航空数据网站 FlightAware 统计，周日全美已有逾5,200个航班受影响，其中逾1,600个航班取消、近3,600个航班延误；周六全美取消逾6,400个航班、延误逾8,000个。交通部长 Sean Duffy 周日在美国广播公司（ABC）《This Week》节目中预计，航班周日逐步恢复、「到周一大概才能完全正常」，与联邦航空管理局（FAA）此前所称周日晚恢复正常的说法相比，完全恢复的时间又往后推了一步。

Duffy 说，目前没有网络攻击或其他恶意行为的证据，但事故根源仍未查明。他披露，FAA 承包商 L3Harris 在阿肯色州 El Dorado 一处设施更换路由器后，触发了得克萨斯州 Amarillo 一台近期更换过的路由器向外广播、把数据灌入全美其他航路管制中心的路由器；FAA 已停用肇事路由器的相关功能，并对空管系统中约60台同型路由器作了同样处理。Duffy 说，安装路由器的工人「是一位爱国的美国人、我们相信是退伍军人，不认为有人蓄意破坏网络，但我们确实还没有找到根本原因」。他还说，出问题的路由器购于2001年、2006年就已过时。

这场扰动源于 FAA 11月13日（周五）发出的全国停飞令：离港航班几乎全部停飞近五小时，是2001年9月11日恐怖袭击以来全美航空最长的一次停摆。周日各航司取消比例分化明显：捷蓝航空（JetBlue）取消27%、美国航空（American Airlines）取消13%，西南航空（Southwest）、联合航空（United）与达美航空（Delta）取消比例在3%至5%之间。

总统特朗普周日首次就本轮航班问题公开表态，他在社交媒体上写道：「工作已经开始了，但应该一次做完，不要一点一点挤牙膏。国会必须批准。」Duffy 自周五以来呼吁国会拨款500亿美元升级空管系统，高于他此前提出的300亿美元；国会去年已批准125亿美元用于空管升级。众议院交通与基础设施委员会及航空小组委员会的民主党领衔议员 Rick Larsen 与 André Carson 周六发声明质疑称，去年批准的125亿美元中约110亿美元尚未花出，并问「请再向国会解释一次，为什么还需要更多钱」；Duffy 周日回应称，去年那笔钱只指定了特定用途，不包括管理空域的新软件。

Follow-up: U.S. Flight Disruptions Enter Third Day With 1,600 Sunday Cancellations; Duffy Says Fully Normal by Monday

U.S. flight disruptions entered a third day on November 15. More than 5,200 flights nationwide had already been affected on Sunday, with more than 1,600 canceled and almost 3,600 delayed, according to aviation data site FlightAware; on Saturday airlines canceled more than 6,400 U.S. flights and delayed more than 8,000. Transportation Secretary Sean Duffy said on ABC's "This Week" that flights would come back to normal on Sunday "but probably fully normal" on Monday, pushing the full-recovery timeline back from the Federal Aviation Administration's earlier expectation of Sunday evening.

Duffy said there is no evidence of a cyberattack or other malicious intent, but the cause remained unclear. He said the replacement of a router at an FAA facility in El Dorado, Arkansas, triggered problems with a recently replaced router in Amarillo, Texas, which started broadcasting and overloading routers at other air traffic control centers across the country. The FAA has disabled the functionality of the originating routers and did the same for about 60 similar routers in the air traffic control system. "The worker who installed the router was a good American patriot, we believe, a veteran — so we don't think that someone tried to sabotage the network on the install," Duffy said. "But we don't actually have the root cause." He said the routers that experienced issues were purchased in 2001 and were obsolete by 2006.

The disruption began with the FAA's nationwide ground stop on Friday, November 13, which halted nearly all departing flights for almost five hours — the longest nationwide halt to U.S. air travel since the September 11, 2001 attacks. Cancellation rates diverged sharply on Sunday: 27% of JetBlue flights and 13% of American Airlines flights were canceled, with Southwest, United and Delta reporting cancellations of 3% to 5% of their flights.

President Donald Trump on Sunday made his first public comments on the weekend's air travel issues, writing on social media: "We have already started the work, but it should be done all at once, not in drips and drabs. Congress must approve." Since Friday Duffy has called for $50 billion in funding to upgrade air traffic control systems, up from his earlier request of $30 billion; Congress approved $12.5 billion last year. Representatives Rick Larsen and André Carson, the top Democrats on the House Transportation and Infrastructure Committee and its aviation subcommittee, said in a statement on Saturday that about $11 billion of the $12.5 billion approved in 2025 remains unspent, asking, "Explain to Congress, again, why they need more money?" Duffy said on Sunday that the money allocated last year was earmarked only for certain spending and does not include funds for new software to manage the airspace.
