Driving Sunday AM Las Vegas-
 

Ontario,CA Airport.Can I we drive it in 3 hours if we leave Vegas at,say,0700?

Well, I think you would have to average about 85 miles per hour door to door. Are you comfortable with that?

Yes you can do it in 3, but to be safe plan on 4. Why rush, on the road always allow time for the unexpected specially if you have a plane to catch.

3 hours is pushing it but barely doable if you are a fast driver and don't stop. I'd say 3 1/2 hours is about right if you drive about 70-75 and traffic is light.

Honestly, hop on a Southwest Airlines flight and FLY it instead of driving!

Are you still trying to make that 11:40 flight out of ONT? Didn't you like the answers you go tlast time you asked this question? The drive is still the same, sorry
