About
Frontier Airlines is a major American ultra-low-cost carrier (ULCC) headquartered in Denver, Colorado. Founded in 1994, the airline operates over 100 destinations across the United States, Mexico, Caribbean, and Central America. Frontier is known for its distinctive aircraft livery featuring wildlife on each tail.
As an ULCC, Frontier's base fares are among the lowest in the industry—but nearly everything beyond a seat and small personal item costs extra. For flexible travelers with minimal baggage, Frontier can deliver genuine value. For those needing bags and seat selection, compare the total cost to legacy carriers before booking.
Frontier is not affiliated with any airline alliance.

Tips & Tricks
Booking:
- Always compare TOTAL cost (base fare + bags + seats) vs. legacy carriers
- Check the bundle deals—sometimes bags + seats bundle saves money
- Book bags at initial purchase for lowest price
- Tuesday sales often feature route-specific deals
Packing:
- Measure your personal item—it will be checked at the gate
- Consider a checked bag instead of carry-on (often cheaper)
- Pack a fully charged phone—no outlets on board
- Bring snacks and entertainment
At the Airport:
- Check in online to avoid $25 airport fee
- Arrive early—boarding is competitive for overhead space
- If you have no carry-on, board with later groups (no bin space needed anyway)
Maximizing Value:
- Frontier works best for: simple trips, no bags, flexible travelers
- Compare total cost before assuming ULCC is cheapest
- Match elite status from other airlines for instant Gold (promotional)
- The Frontier credit card accelerates status earning
Upgrade Strategies:
- Stretch seats can be bought at check-in if available
- UpFront Plus guarantees empty middle seat
- First Class coming late 2025
Avoid These Mistakes:
- Showing up with an oversized "personal item" (gate fee is steep)
- Buying bags at the airport instead of online
- Expecting any amenities—bring everything you need
- Assuming overhead bin access without a carry-on purchase
