Booked a roundtrip with priceline which included frontier airlines. Horrible flights which h they charge you $42 for carry on bag. Wont let you choose seat unless you pay more. Staff was absolutely rude to my wife who is hard of hearing. I should have booked somewhere else. Flight comfort horrible. It's like flying a Nazi airline. The tone of the flight attendants was horrible. A small carry on backpack $42. Robbery
