Best Budget Airlines
Cheap fares, judged on what happens after you book
Low-cost carriers are scored on the same disruption-first logic as the flagship list, adjusted for what a budget fare actually promises. Ancillary fees are not penalised on principle — an airline that is transparent about what costs extra is treated very differently here from one that buries it. Seat pitch and comfort still count, but nobody expects a $40 fare to deliver a lie-flat seat, so that criterion carries less weight than it does on the full-service list.

The top three
Leading the list
Rank 01Editor’s pick
Southwest Airlines
United States · est. 1967
Built the point-to-point low-cost model that most budget carriers worldwide still copy, and its no-change-fee policy remained a genuine outlier in US aviation for decades. A 2022 holiday-season meltdown exposed real scheduling-software fragility that the airline has spent heavily to fix since.
97.5/100 Top 49 score—No changeRank 02Editor’s pick
JetBlue
United States · est. 1998
Free seatback entertainment and the most generous seat pitch of any US low-cost carrier set a genuinely different tone from the ultra-low-cost end of the market it is sometimes grouped with. Northeast US weather and congested airspace produce real, recurring delay exposure the airline cannot fully control.
94.9/100 Top 49 score1Down 1Rank 03Editor’s pick
IndiGo
India · est. 2006
Became India’s dominant domestic carrier through relentless operational discipline and a young, standardised A320 fleet that keeps maintenance predictable at scale. Rapid growth has occasionally outpaced crew and ground-staff hiring on newer routes.

- Rank 13. Allegiant Air. Score 76.2 out of 100.NewNew entry
Allegiant Air
United States · est. 1997
Built around leisure routes from smaller US cities directly to vacation destinations, flying older aircraft on lower-frequency schedules than most competitors, which keeps costs down but leaves less operational slack when something goes wrong. Genuinely useful for routes larger carriers have abandoned entirely.

Frontier Airlines
United States · est. 1994
An ultra-low-cost US carrier built on an unbundled fare model where the advertised price is rarely close to the final one once bags and seat selection are added. Fleet fuel efficiency is genuinely strong, a rare area where the airline’s cost-cutting focus produces a real customer-facing benefit.

Spirit Airlines
United States · est. 1980
The most aggressively unbundled fare model in US aviation, where literally every extra — bags, seat assignment, printing a boarding pass at the counter — carries a separate charge disclosed at each step of booking rather than upfront. Went through Chapter 11 bankruptcy restructuring, which has visibly strained its operational reliability during the process.

Wizz Air
Hungary · est. 2003
Central and Eastern Europe’s dominant ultra-low-cost carrier, expanding aggressively into new markets faster than its ground infrastructure and crew base have sometimes been able to support. Base fares remain genuinely the lowest across much of its network, but disruption recovery has drawn real, repeated regulatory criticism.

How this list is scored
Four criteria, weighted before the first entry
Fee transparency is scored on how clearly total cost is disclosed at booking, not on whether fees exist at all — ancillary pricing is the low-cost business model, not a flaw in itself.
- Disruption handling 30%
- Rebooking speed and communication when a low-cost schedule goes wrong, where thin schedule buffers make this hardest.
- Value for price 25%
- What the all-in cost delivers once realistic ancillary fees are included.
- On-time performance 25%
- Departure and arrival punctuality across the network.
- Fee transparency 20%
- How clearly the true cost of a trip is disclosed before payment, not buried in later steps.
Questions
About this ranking
Why does Ryanair rank low despite strong on-time performance?
On-time performance is genuinely strong, but disruption handling and fee transparency both score poorly enough to offset it — a well-documented pattern of aggressive ancillary charges and slow irregular-operations communication pulls the overall score down.
Is a low-cost carrier automatically penalised for charging for bags and seats?
No. Fee transparency scores whether those costs are disclosed clearly at booking, not whether they exist. Charging for a bag is the business model; hiding the true cost until checkout is the actual problem.
Why does seat pitch carry less weight on this list than the flagship airlines list?
Because a tight-pitch, no-frills seat is the honest trade-off of a genuinely low fare. Penalising every budget carrier equally for it would not distinguish a good one from a bad one.
Do these airlines fly long-haul routes?
A few do on a limited basis, but this list is built primarily around short and medium-haul point-to-point flying, which is where the vast majority of low-cost capacity actually operates.
