I was wary to fly after reading all of the negative reviews. If you pay attention when you are booking you wont have a problem with the charges. After booking and with extra charges, the flight was still half the cost of all other airlines.
The airplane is smaller and less comfortable but for the quick flight from Vegas to Fresno, it was manageable. Service was polite and friendly.
I got exactly what I expected based on price and would fly again for any flight less than 2 hours.
