A government shutdown could really stress out the air travel system — and its passengers

. A government shutdown could mean that the Federal Aviation Administration is not fully functioning, which could delay flights due to lack of personnel. Essential personnel like air traffic controllers may still be available, though their paychecks might be delayed. The TSA could also be impacted, meaning delays and more scrutiny at the security checkpoint. Finally, a government shutdown could also impact services like airline customer service, as typically those services are provided in part by the government.
