A budget airline comparison is not as simple as comparing base fares. Two airlines flying the same route for nominally similar prices can have vastly different total costs once bags, seat selection, meals and payment fees are added — and vastly different punctuality, safety records and customer service quality.
This guide evaluates each major LCC (low-cost carrier) on four criteria: true all-in pricing, fleet age and safety record, punctuality statistics, and customer service quality when things go wrong.
Ryanair carries over 180 million passengers annually — more than any other European airline. Despite its notorious reputation for fees and discomfort, the numbers keep growing because on many routes it is genuinely the cheapest option by a significant margin.

Weaknesses:
True cost calculation example (London to Barcelona):
When Ryanair makes sense: Short trips with carry-on luggage only, flexible on exact airports, not carrying large bags. Saving £40–£80 vs a full-service airline is real for a 2-hour flight.
easyJet occupies a middle position between Ryanair's aggressive fee structure and full-service carriers. Cabin bags are included in most fares, customer service is notably better, and it primarily uses main airports rather than secondary alternatives.
Strengths:
Weaknesses:
Best routes: London → Nice/Barcelona/Amsterdam; Amsterdam → European leisure destinations
Wizz Air has aggressively expanded from its Eastern European base to cover routes across Europe, the Middle East and North Africa. Its combination of genuine low fares and modern Airbus A320neo fleet makes it compelling for specific routes.
Strengths:
Weaknesses:
AirAsia operates across Southeast Asia, connecting 165+ destinations in the region that were previously served only by expensive full-service carriers. It fundamentally transformed travel accessibility across the region.
Key routes: Kuala Lumpur → Bangkok/Singapore/Jakarta/Manila/Bali and hundreds more
Fleet: Airbus A320 family (young fleet with A321neo deliveries ongoing)
Ancillaries: Baggage (from MYR 50), meals (MYR 15–35), hot seats with extra legroom
True value: Genuinely cheap fares on regional routes; base fares of RM59–RM99 are regularly available for 1–2 hour Southeast Asian routes
IndiGo carries over 50% of India's domestic air passengers — a market share dominant enough to make it unavoidable for anyone flying domestically in India.
Strengths:
Weaknesses:
Booking: indigo.in; accepts Indian payment methods + international cards
Scoot fills the medium and long-haul LCC niche, connecting Singapore to destinations across Asia, Australia and the Middle East at prices significantly below SIA's mainline product.
Notable routes: Singapore → Tokyo, Sydney, Berlin, Athens, Amritsar
Fleet: Boeing 787 Dreamliner — genuinely comfortable for an LCC long-haul option
Best value: Singapore → Australia routes where Scoot is typically 30–50% cheaper than Qantas or SIA
Spirit takes the budget airline model to its logical extreme — the lowest possible base fares with fees for almost everything else.
What is included in the base fare: Your body and one personal item (fits under seat, maximum 45x35x20cm)
What costs extra: Everything else — carry-on bag ($55–$85), checked bag ($45–$75), seat selection ($5–$50+), water on the plane ($3)
When Spirit makes sense: One-way trip with only a small backpack; fares sometimes $30–$60 cheaper than alternatives even after adding one carry-on.
Frontier has recently shifted to an ultra-low-cost model similar to Spirit but with newer aircraft and marginally better reputation.
The Discount Den: Frontier's subscription service ($60/year) gives access to the cheapest fares — members-only fares sometimes 30–50% below standard prices. Good value for frequent US domestic travellers.
Before booking any budget airline, run this calculation:
Compare this total against a full-service alternative. On routes under 3 hours, budget airlines typically win by $30–$100. On routes over 5 hours where a meal, legroom and recline matter, the gap often narrows significantly or disappears.
| Airline | On-Time Performance | Notes |
|---|---|---|
| Jet2 (UK) | ~88% | Leisure specialist; consistently best in UK |
| easyJet | ~78% | Strong for a major LCC |
| Ryanair | ~73% | Variable by route and season |
| Vueling | ~70% | Barcelona-based; frequent delays in peak summer |
| Wizz Air | ~68% | Weakest among major European LCCs |
A flight that is consistently 45–60 minutes late has a real cost in missed connections, late hotel check-ins, and wasted time. Factor punctuality into route decisions, especially for connections.
