Can I use my drivers license as id to board a plane?

For the short-term you can but in the near future you're going to need a new type of ID they're issuing

United States license issued by one of the States for non international flights.

Thank you for contacting the airport. The airport understands that drivers license are still being used for identification at time of check in. We suggest you double check with TSA and Allegiant for the rules/regulations.
