Over 7,700 flights were delayed and nearly 2,300 canceled in the United States on Sunday as the government shutdown’s impact on air travel grows more significant ahead of the holidays.

The largest number of outright cancellations happened at Atlanta’s Hartsfield-Jackson International Airport as of Sunday afternoon, which saw 323 flights delayed and 192 flights canceled by shortly before 5 p.m. EST.

Delays also throttled traffic originating at New York City’s regional airports, with 299 at LaGuardia (56% of flights), 236 delays at Newark (40% of flights) and 204 at John F. Kennedy (31% of flights).
