i just received a temporary drivers license. does anyone know if I can fly to Texas out of Ontario airport in Calif. I'm flying from Calif. to Texas and I only have a temporary drivers license..Will I be allowed to board the plain?

What type of document(s) did you provide to get the temporary drivers license? Does the license have your picture on it? How soon does it expire?
If you have a credit/debit card with the same name on it, you probably can.

Temp licenses do not have photos.

I suggest you read the official rules here: https://www.tsa.gov/travel/security-...identification

If you notice there is provision about flying without having an official ID document . . . I would get to the airport earlier than you normally would for the potential extra screening.

(do you have a passport by any chance? I assume not)

Definitely arrive early and take (ideally) your old expired license (or even a Costco card) ... just something that has your identity and a photo. That will generally do the trick. A passport or passport card always works for domestic travel as well.
