Critical Points: Smart Traveler's Handbook
The Low-Cost Factor (Frontier)
User Experience: Frontier is often described as the "black sheep" at DEN. Passengers report frequent cancellations, unempathetic counter staff, and extreme strictness regarding carry-on luggage.
Strategy: If you are flying with budget airlines, print your boarding pass before arriving and measure your luggage at home. Any size error will cost you an extra fee at the gate.
