Which of the following is a common feature of Frontier's flight experience?

Frontier Airlines is known for its low-cost model, which emphasizes affordability and allows passengers to customize their travel experience. A common feature of Frontier's flight experience is the basic seat with optional upgrades available. This approach aligns with the ultra-low-cost carrier strategy that Frontier follows, where the base fare covers essential services, and additional amenities, like larger seats or extra legroom, can be purchased as upgrades.

While complimentary meals, entertainment systems in every seat, and guaranteed window and aisle seat selection may enhance the flying experience, they do not typically reflect Frontier's business model. Frontier opts for minimal amenities at the base price to keep fares low, while giving passengers the flexibility to pay for additional features and services as they desire. This model is designed to appeal to budget-conscious travelers who prioritize cost over frills.
