What's open on Labor Day? Most retailers. Closed? Government, banks and the stock market.

Most government services will shut down for Labor Day, while the retail sector remains broadly open. In Washington, government offices, post offices, courts and schools are listed as closed. U.S. stock markets and banks are also closed on Monday. Standard FedEx and UPS pickup and delivery services won’t operate on Labor Day, though some critical services may run at select locations. Retailers like Costco will be closed, but major national retailers and grocery stores generally stay open, with many offering promotional sales. For travel, AAA expects flight prices to top domestic destinations to be nearly 20% higher than last year, and average gas prices to be just under $4.10 per gallon, about 90 cents higher year-on-year, while cruises from U.S. ports are about 4% cheaper. AAA advises travelers to check weather and inspect vehicle tires, battery, and fluids, and to carry an emergency kit.
