More than 1,400 flights were canceled on Tuesday amid the ongoing U.S. government shutdown, which has entered its fifth day. The shutdown, caused by political disagreements in Congress, has severely impacted air travel, with airlines warning that flight schedules will not immediately recover even if the government reopens. Although the Senate has passed a bill to reopen the government and the House is set to take up the measure, airline officials and industry experts forecast that flight disruptions and delays could worsen by the end of the week. The shutdown has also led to widespread travel chaos, with airports like Atlanta's Hartsfield-Jackson experiencing significant delays and cancellations. Despite political efforts to resolve the shutdown, airlines emphasize that it will take time for travel operations to return to normal. The situation underscores the ongoing impact of political gridlock on essential services and daily life.
