Frontier Airlines is an ultra-low-cost carrier (ULCC) based in Denver, Colorado, operating an all-Airbus fleet (A319, A320, A321) across primarily domestic US leisure markets. Frontier's business model separates the base fare from virtually all ancillary services — seat selection, carry-on bags, and checked bags are all priced separately. Travelers who pack light and book bundles (The Works, The Perks) strategically can find excellent value, while those who add fees at the gate often pay more than legacy carriers. Frontier is one of the few US airlines offering a subscription-style pass for unlimited or heavily discounted travel.

In-Flight Wi-Fi
Not available on most Frontier flights
Cost: Not applicable — Frontier does not currently offer in-flight Wi-Fi on the majority of its routes
Frontier has historically prioritized cost reduction over onboard amenities, and in-flight Wi-Fi is not a standard feature. There is no seat-back entertainment; passengers are encouraged to bring their own devices and download content before boarding. Some aircraft may have limited connectivity on select routes.
Pro Tips
- Calculate total trip cost before booking — carry-on bag fees ($25–$99 depending on when purchased) and checked bag fees can exceed the base fare if added at the airport. Bundle fees into The Works at checkout for the best per-item price.
- The Works bundle is Frontier's best value for travelers checking a bag: it includes a carry-on, checked bag, seat selection, flight flexibility (same-day changes), and a refund option — all for less than buying each item separately.
- UpFront Plus seats in rows 1–2 include a blocked middle seat — effectively two seats for the price of one upgrade — making it Frontier's closest equivalent to a premium product.
- Frontier's GoWild All-You-Can-Fly Pass provides unlimited same-day or advance booking on most domestic routes. Best used by travelers with flexible schedules who can book last-minute.
Frequently Asked Questions
Does Frontier Airlines charge for carry-on bags?
Yes — carry-on bags that go in the overhead bin are not included in Frontier's base fares. Fees range from $25 (booked far in advance online) to $99 (paid at the gate on day of travel). A personal item (under the seat, up to 14×18×8 inches) is always free. Purchasing bags at checkout or as part of The Works bundle is significantly cheaper than paying at the gate.
Does Frontier have Wi-Fi?
No — Frontier does not currently offer in-flight Wi-Fi on most of its routes. There is no seatback entertainment either. Frontier's low-cost model focuses on minimizing operational complexity, and in-flight connectivity has not been part of its standard offering. Download movies and music to your device before boarding.
What is Frontier's GoWild All-You-Can-Fly Pass?
GoWild is Frontier's subscription flight pass available as an annual or summer pass. It allows cardholders to book unlimited flights on most domestic Frontier routes, with same-day bookings often available at no additional cost. It is best suited for travelers with flexible schedules who can book last-minute and live near a Frontier hub.
What seats have the most legroom on Frontier?
UpFront Plus seats in the first 1–2 rows of A320/A321 aircraft have 37 inches of pitch and include a blocked middle seat. Stretch Seats in the exit rows offer approximately 35–38 inches of pitch. Standard economy seats have a tight 28–29 inches of pitch, which is among the smallest of any US carrier.
What airports does Frontier operate from?
Frontier's headquarters and largest hub is Denver International Airport (DEN). It operates heavily from Las Vegas, Orlando, Atlanta, Chicago (Midway and O'Hare), Phoenix, and many secondary markets. Frontier focuses on point-to-point leisure routes rather than a traditional hub-and-spoke network.
