Standardized (and shrinking) airline seats have made it difficult for people of all shapes and sizes to fit into an occupied space with set dimensions, because not everybody can fit comfortably. However, not all airline seats are created equal.

Spirit Air is an ultra low-cost airline that’s earned a bit of bad rap, some of it well-deserved. Its 28-inch pitch is the worst in the industry, and they charge for just about everything on board. However, Spirit’s burning desire to upsell extra services can be used to your advantage.

For a small fee you can get a seat that by just about every measure is first-class quality. Spirit’s calls it the Big Front Seat.

Premium economy is more expensive than coach, less expensive than business and far cheaper than first class. It’s becoming a popular choice among airline travelers.
