没有id可以飞。但是如果身份过期，有可能会招来麻烦吧。 https://www.skyscanner.com/tips-and-inspiration/what-to-do-if-you-lose-your-id-traveling Can you fly without an ID? The short answer: YES. If you’re catching a domestic flight within the US and your ID is lost, stolen or you left it at home, you might be in luck. The Transportation Security Administration (TSA) has other ways of confirming your identity using publicly available databases, so there’s a good chance you’ll be allowed on your flight. First, though, you’ll need to complete an identity verification process with a TSA officer — so arrive at the airport well ahead of your flight’s scheduled departure for the best chance of making it in time for take-off. (We’d recommend AT LEAST two hours ahead.) The TSA officer will ask for info, including your name, current address and other personal details that can be used to confirm that you are who you say you are. The process could take a while. If they’re able to confirm your identity against a database, you’ll be allowed through to the security screening. (You’ll get a boarding pass with a note on it explaining that you don’t have ID). If, however, your identity can’t be verified, they’ll have no choice but to turn you away. (A day weeping under the covers it is, then).

曾经没有ID（恰巧丢了）也幸运地被允许登上了飞机，但现在不知道有没有变严格
