“I have only flown one trip with Frontier Airlines. Outbound they canceled my flights which stranded me in Denver when the final destination was Atlanta. I had to buy a United Airlines ticket to get to Atlanta. I was told I would receive a full refund, but that never happened (fraud?). I purchased the same return ticket again and had a 3-4 hour delay in Atlanta while they flew in a pilot from another city to fly the plane! Expect your personal item to be checked for size on most flights – you will pay more to take it onboard if it is too big. They are at the bottom of my choice of airline for flying now.”
