Frontier or United?
I have a trip from Chicago to Denver coming up. UA and F9 both have an early morning flight on an A319. Both are around the same price. MDW is slightly more convenient than ORD, but the UA flight is slightly earlier...
I have low-level elite status on UA, and have never flown F9 before.
Should I give Frontier a shot? Is there any food service to speak of? How does the Denver terminal compare to UAs?
