I'll be traveling to Dallas TX, but I'm still waiting for the state of Illinois to send me my hard copy of my driver's license all they gave me was a piece of paper with my picture on it. Can I still fly?
The TSA's requirements list various forms of acceptable identification. However:
A temporary driver's license is not an acceptable form of identification.
If you have one of the other documents on that list, you're all set.
If not, you can attempt to fly without ID:
If you’re willing to provide some additional information, we have other means of substantiating your identity, such as using publicly available databases. If we can confirm your identity, you’ll be cleared to go through security, and you may or may not have to go through some additional screening.
If we can’t confirm your identity with the information you provide or you’re not willing to provide us with the information to help us make a determination, you may not be able to fly. Regardless, if you do not have ID, please allow extra time for check in. We would not want you to miss you flight.
The process will take extra time and will require some personal information. They'll ask you some security questions, and if they're able to verify your identity, you'll be allowed through, usually with extra screening. If you have other forms of identification, such as other forms of photo ID the TSA doesn't normally accept (even a Costco or Sam's Club card if you have one), it wouldn't hurt to bring them along. This procedure is not guaranteed, and you could be refused if they can't verify your identity.
If possible, I'd check in online, so at least you have your boarding pass without being asked to show ID.
