Airlines are canceling hundreds of flights to comply with the FAA's order. But there are still questions about the plan, which the agency says will keep the skies safe during the government shutdown.

The two major airports in North Texas will lose flights should the Federal Aviation Agency follow through with a 10% reduction in air traffic at some of the nation's busiest airports.

As flights continue to be canceled amid the shutdown, that could affect air cargo – which could eventually ripple into the supply chain and holiday deliveries. Here’s what to know.

Airlines at Orlando International Airport (MCO) have reported 41 projected flight cancellations for today, November 9th, due to the FAA’s flight reduction order. The cancellations are part of a wider effort by the FAA to handle air traffic and maintain safety, although the exact reasons for the reduction order have not been made public.

The refund policy for Delta’s cancelled flights does allow reimbursement but not for all expenses. Delta Air Lines is experiencing daily flight cancellations like many U.S. carriers. That’s, in part, due to the Federal Aviation Administration mandating flight reductions as the government shutdown continues.

The government shutdown has triggered 1,000-plus flight delays as the FAA cuts capacity at 40 airports. Airlines are offering refunds and policy changes amid ongoing travel disruptions.
