London Luton sets the tone for Wizz Air's UK record in 2025: it handled 39,003 flights, two thirds of the total, and the share of flights 3+ hours late or cancelled is the same, 1.2% (the London Luton breakdown). That is below the national average (1.6%), but there is a weak link.
Wizz Air's three operators: the UK one slips up most often
The UK Civil Aviation Authority (CAA) counts flights by operator. Wizz Air UK, which holds a UK Type A operating licence, had 1.6% of its 26,831 flights 3+ hours late or cancelled; Wizz Air 0.7%, Wizz Air Malta 0.9%. At easyJet it is the other way round: the UK operator is the more reliable one. Wizz Air UK had 294 flights 3+ hours late and 128 cancellations: a long wait in the terminal is more likely than a cancellation.
If your departure is delayed
On flights of up to 1,500 km, the right to care starts at 2 hours: food and drink, two phone calls or emails, and accommodation with transport to it if the delay runs overnight. After 5 hours you can choose not to travel and get a refund. Compensation (£220) applies only when you arrive at your final destination more than 3 hours late (CAA rules).
