Frontier AirlinesF9
US ULCC with Denver hub and Rocky Mountain leisure routes
Frontier Airlines scores 54/100 — ranked 74 of 102 profiled carriers
GOOD FIT IF
- You're flying a short US leisure route where the base fare is the deciding factor
- You travel with a personal item only — Frontier Airlines charges for bags, seats, and most extras
- United States is where Frontier Airlines is densest; pick a nonstop if one exists
THINK TWICE IF
- Economy seat pitch and density get frequent complaints — check aircraft type before you commit
- Baggage fees and gate enforcement are forum flashpoints — price the all-in cost
- Ancillary fees for bags, seats, and priority boarding can erase the fare savings
- IRROPS recovery is thin — missed connections are often treated as separate tickets
- You're tall or need workspace — expect 28–29" pitch on most aircraft

Cabin experience
Economy
No-frills seats with tight pitch — budget for bags, seats, and snacks
Business
Lie-flat and service quality depend heavily on route and aircraft
Traveler sentiment
Forum patterns, negativity-adjusted
Travelers expect minimal service — crew is functional, not attentive
Tight seats by design; pay extra for legroom where available
App covers basics — check-in and add-on purchases; limited disruption tools
Low fares with strict change and refund rules — read fare conditions carefully
Boarding is typically orderly on most routes
Carry-on and checked bags often cost extra; read fee schedule before booking
Mostly self-serve support; expect long waits during mass disruptions
Limited rebooking options during mass-cancel events
