Frontier Airlines vs. Other Budget Airlines – Which One Should You Choose?

Frontier Airlines vs. Other Budget Airlines – Which One Should You Choose?

In today’s fast-paced world of travel, budget airlines have become a go-to option for many travelers seeking affordability without sacrificing the essentials. Among these, Frontier Airlines stands out as a prominent ultra-low-cost carrier in the United States. But how does it compare to other budget airlines like Spirit, Allegiant, and Southwest? If you’re wondering which airline deserves your money and trust, this article will help you decide.

Let’s dive deep into the comparison and understand which budget airline aligns best with your travel needs.

Understanding the Budget Airline Model

Budget airlines operate on a no-frills model. This means you get a basic flight ticket, and everything else—checked baggage, seat selection, food, and even carry-ons in some cases—is considered extra. These carriers focus on minimizing costs and passing on the savings to customers through low fares.

What Sets Frontier Airlines Apart?

Frontier Airlines is well-known for its extremely low base fares, which can be very attractive, especially for flexible travelers. Its slogan, “Low Fares Done Right,” reflects its commitment to affordability. With a hub in Denver, Frontier flies to more than 100 destinations across the U.S., Mexico, and the Caribbean.

Here’s what makes Frontier unique:

  • Ultra-low base fares: Perfect for budget-conscious travelers.

  • "A La Carte" pricing: You only pay for what you need.

  • Discount Den membership: Offers exclusive fares and early access to sales.

  • Eco-friendly practices: Frontier is proud of its modern, fuel-efficient fleet.

However, these low fares come with trade-offs, particularly in terms of in-flight comfort and amenities.

Comparing Frontier Airlines to Other Budget Carriers

Let’s break down how Frontier compares to three other major budget airlines in the U.S.—Spirit Airlines, Allegiant Air, and Southwest Airlines.

1. Frontier vs. Spirit Airlines

These two are often compared as they follow a similar business model. Spirit also offers ultra-low-cost fares with strict à la carte pricing.

  • Fares: Both airlines are competitive, but Spirit occasionally offers lower promotional rates.

  • Fees: Spirit’s baggage and seat selection fees can be slightly higher.

  • Comfort: Frontier’s seats do not recline, while Spirit has slightly more padding on newer aircraft.

  • Customer Service: Both have mixed reviews, but Frontier has recently made efforts to improve service.

2. Frontier vs. Allegiant Air

Allegiant serves smaller cities and focuses on leisure destinations, often with limited flight schedules.

  • Route Network: Frontier has a broader route map than Allegiant.

  • Flight Frequency: Allegiant flies less frequently, so rebooking after a cancellation might take longer.

  • Onboard Experience: Very similar—basic seating with paid add-ons.

3. Frontier vs. Southwest Airlines

While Southwest is technically a low-cost carrier, it offers more perks than Frontier.

  • Baggage Policy: Southwest includes two free checked bags; Frontier charges for everything.

  • Seat Selection: Southwest allows open seating; Frontier assigns seats for a fee.

  • Customer Service: Southwest ranks higher in customer satisfaction.

  • Pricing: Frontier often has cheaper base fares, but Southwest’s inclusive pricing can be better for those who check bags.

When Should You Choose Frontier Airlines?

Frontier is best suited for travelers who:

  • Travel light with minimal luggage.

  • Are flexible with travel dates and times.

  • Don’t mind paying extra for seat selection and other amenities.

  • Want to fly short distances within the U.S. at the lowest possible cost.

If you fit this profile, Frontier can be a fantastic option. Just be sure to read the fine print and understand all potential fees before booking.

Flyingscanner Tip: How to Maximize Your Savings

To get the best out of Frontier (and any budget airline), Flyingscanner recommends booking as early as possible and considering their annual Discount Den membership.

Pros and Cons of Frontier Airlines

  • Extremely low base fares.

  • Large and growing network.

  • Eco-friendly operations.

  • Great deals with membership options.

Cons:

  • High baggage and seat selection fees.

  • Customer service can be inconsistent.

Final Verdict: Which Budget Airline Should You Choose?

There’s no one-size-fits-all answer. If you're a light traveler and want the lowest possible fare, Frontier Airlines could be your best bet. But if you're carrying more luggage, value in-flight comfort, or need flexible customer support, Southwest or even Spirit might be worth considering.

Use tools like Flyingscanner to compare not just the base fares but also the total cost after add-ons. This way, you can avoid any surprises and travel smart.

Conclusion

Choosing the right budget airline depends on your specific travel style and priorities.
