May schedules data from Innovata shows Scandinavian budget carrier Norwegian adding capacity at the fastest rate among low-cost carriers.
Norwegian lifted its capacity, as measured in ASKs, by 42% in May compared to the same month last year. It reflects the carrier's recent expansion, which includes its latest base at London Gatwick. Norwegian's traffic, as measured in RPKs, was up 36% in April on nearly 40% higher capacity.
The May figures show other fast-expanding carriers from rapidly developing markets including Pegasus Airlines in Turkey, Indonesian operator Lion Airlines and UAE carrier FlyDubai. Spanish operator Vueling was also among the fast-expanding carriers, reflecting its continued development out of Barcelona. The airline last year outlined plans to add 28 new destinations this summer from its main base.
Southwest Airlines remains the largest low-cost carrier, even more so when its AirTran unit is included. The airline was the fifth largest of all airlines by capacity in May, while Irish budget giant Ryanair also ranks in the top ten airlines by ASKs.
Innovata schedules data for May shows the 50 largest low-cost carriers increased capacity at more than double the rate - 10.8% compared to 5.3% - of the 50 largest airlines overall, albeit off a smaller base.
