You'll soon need a Real ID to fly in U.S. Here's how to get one.

Flying within the U.S. will soon require an extra document that's more secure than a state-issued driver's license or ID if you don't want to lug around your passport with you. 

Beginning in May of next year, all U.S. travelers will be required to have the official document, known as a Real ID, on hand when traveling domestically by air. As an alternative, they may carry their passports with them. 

The initiative is a long time coming. It was initially slated for enforcement beginning in May 2023, but the deadline was pushed back due to the COVID-19 pandemic.
