Can I travel across a state without a passport by plane?
Intra-state, possibly. Inter-state is trickier. You will need a smart ID or a Passport to travel by plane across state lines. Also, check out the CDC website and the state or local health departments websites to learn about Covid-19 travel restrictions, quarantine requirements, or lockdowns. It may be a good idea to renew your passport. As an adult, it will not expire as quickly.
