The Best Budget Airlines Flying From the UK to Europe (2026)

“Budget airline” covers a multitude of sins — from the genuinely excellent to the flying experience you’d pay to forget. If you’re asking what are the best budget airlines flying from the UK to Europe, here’s the honest ranking: who flies where, what they really charge once the extras pile on, and which to pick for your trip.

The Big Four, Ranked

1. Jet2 — the people’s champion

Consistently top-rated in UK customer surveys (Which? Recommended Provider multiple years running). Strengths: genuinely friendly service, generous 22kg hold allowance often included in package deals, UK bases including regional airports, excellent on-time performance. Weaknesses: smaller network than Ryanair/easyJet, focused on leisure destinations (Spain, Greece, Turkey, Canaries). Pick Jet2 when: flying to Mediterranean holiday destinations, especially as a package — their flight+hotel+transfers bundles are often unbeatable. See package vs DIY booking.

2. easyJet — the reliable workhorse

The UK’s biggest budget carrier by network. Strengths: huge European network from many UK airports, decent on-time record, allocated seating standard, the app is excellent, flexible fare options. Weaknesses: the headline fare is never the real fare — baggage, seats and priority add up fast; customer service is functional rather than warm. Pick easyJet when: you want choice of destinations and times, especially city breaks — see cheapest European city breaks.

3. Ryanair — cheapest, with caveats

Europe’s biggest airline, often the absolute cheapest fare. Strengths: unbeatable headline prices (£20 returns happen), massive network, improved punctuality, the 737 fleet is modern. Weaknesses: the full Ryanair experience — strict baggage enforcement, scratchcard sales patter, remote airports (“Barcelona” = Girona, 90 mins away), and customer service that’s legendarily unsympathetic when things go wrong. Pick Ryanair when: price is everything and you’re travelling light with flexible plans. Read the baggage rules twice — the £50 gate bag fee wipes out the saving.

4. Wizz Air — the eastern specialist

Hungarian carrier, big at Luton and Gatwick. Strengths: cheapest fares to Eastern Europe (Poland, Romania, Hungary, the Baltics), modern Airbus fleet. Weaknesses: smaller UK network, customer service complaints, ancillary fees add up. Pick Wizz when: flying east — often half the price of alternatives on routes like London-Warsaw or London-Bucharest.

The Smaller Players Worth Knowing

• Vueling — Spanish carrier (IAG-owned), good for Spain from the UK, reasonable service.
• Eurowings — Lufthansa’s budget arm; decent for Germany.
• Norwegian — rebuilt post-pandemic, focused on Nordics; worth checking for Scandinavia.
• British Airways (Euro Traveller) — not “budget,” but BA’s short-haul economy often matches budget fares on competitive routes — with Heathrow slots, free seat selection for status holders, and better disruption handling. Always compare.

The Real Price: Beating the Extras Game

Budget airlines profit from extras; beat them at it: travel hand-luggage only when possible — see travelling with hand luggage only. Never pay for seat selection unless you must sit together (families with young kids get seated together free by policy on most). Check in online (Ryanair charges £55 at the airport — not a typo). Bring food — airport meal deals beat £8 paninis. Measure your bag — sizers at gates are not decorative. Book direct — third-party sites add fees and complicate changes. The headline £29 fare with £60 of extras is a £89 fare — compare the total against easyJet/Jet2/BA before booking.

When Things Go Wrong: Know Your Rights

Budget doesn’t mean rightless: EU261/UK261 applies to all flights departing the UK regardless of airline — delays, cancellations and denied boarding trigger compensation (£220-520 depending on distance) plus duty of care (meals, hotels). Airlines must rebook you, including on rivals if needed. Our full guide to flight delay compensation under UK law covers claiming — budget carriers hope you don’t know this; now you do.

Avoiding Roaming Bill Shock on Arrival

Unrelated to airlines but trip-ruining: landing in Europe to a £50 roaming bill. Sort your phone before flying — see avoiding roaming charges in Europe.

Budget Airline Packing Rules Compared

• Ryanair: small personal bag free (40x20x25cm — genuinely small); 10kg cabin bag £12-20; 20kg hold £20-35. Strictest enforcement in the business.
• easyJet: small under-seat bag free (45x36x20cm); large cabin bag £8-30 depending on route; 23kg hold £24-48. Slightly more generous, still strict.
• Jet2: 10kg hand luggage free (56x45x25cm — generous!); 22kg hold often included in packages, £30-40 flight-only. The baggage winner.
• Wizz Air: small bag free (40x30x20cm); 10kg cabin £10-25; 20kg hold £25-45.

Measure your bag against the specific airline’s sizer dimensions — “cabin bag” means different sizes on each. When comparing fares, add the baggage you’ll actually take to each — Jet2’s free 10kg often makes it cheapest overall despite higher headlines. See hand-luggage-only travel for packing light enough to dodge fees entirely.

Loyalty and Memberships: Worth It?

• easyJet Plus (£215/year): only worth it for very frequent flyers (20+ flights) — speedy boarding, free seat selection, extra bag.
• Ryanair Prime / paid memberships: do the maths on your actual flight count; occasional travellers never break even.
• Wizz Discount Club (£30/year): £5 off per flight per person — pays for itself in 3 return flights. Worth it if Wizz is your eastern-Europe carrier.
• The real loyalty hack: airline-agnostic — a fee-free spending card (see travel credit cards) and price alerts beat any single airline’s scheme for leisure travellers.

Whatever you fly, know your rights: the CAA’s guidance for airline passengers explains compensation and care entitlements in plain English.

The Practical Takeaway

Cabin Baggage Rules Compared (Where They Get You)

Baggage is where budget airlines make their real money, and the rules differ enough to change which airline is cheapest for your trip:

• easyJet: one small cabin bag (45x36x20cm) free, fits under the seat. Large cabin bag (56x45x25cm) costs extra unless you buy Up Front/Extra Legroom seats. Hold luggage from ~£24 each way.
• Ryanair: one small bag (40x20x25cm) free — smaller than easyJet’s, and they enforce it with the dreaded bag sizer at the gate. Priority boarding (~£6–12) adds a 10kg cabin bag. Hold luggage from ~£20 each way when booked early, much more later.
• Wizz Air: one small bag (40x30x20cm) free. Wizz Priority adds a larger cabin bag. Hold luggage pricing is dynamic and can be steep close to departure.
• Jet2: 10kg hand luggage included as standard — genuinely generous, and one reason their headline fares compare better than they look.

The practical implications: measure your bag against the specific airline’s sizer dimensions, not “cabin bag” generically — a bag that’s fine for easyJet can fail Ryanair’s smaller gauge. Book hold luggage at initial booking; adding it later (especially at the airport, where it’s £50+) is brutally expensive. And wear your bulkiest items: a coat with big pockets is the budget traveller’s extra bag.

One more trap: weight limits on cabin bags. easyJet has no weight limit on cabin bags (if you can lift it into the locker), Ryanair’s is 10kg for priority bags, and Wizz Air’s 10kg too. A “free” bag that’s overweight at the gate becomes a £50 problem. Weigh at home with the bathroom scales — it takes ten seconds and has saved me more than once.

The best budget airlines from the UK to Europe: Jet2 for service and packages, easyJet for network and reliability, Ryanair for rock-bottom fares (mind the extras), Wizz Air for Eastern Europe. Compare total prices including baggage, travel hand-luggage-only when you can, check in online, and know your UK261 compensation rights. The cheapest headline fare rarely wins — the cheapest total does.
