Alaska Air Group’s regional capacity, mainly operated by its subsidiary Horizon Air, has grown at a much higher rate in 2016. From January through June 2016, regional capacity grew by 22.1% YoY. This is a significant change from the comparable period in 2015, when regional capacity grew by only 5.6% YoY.

What to expect

For 2Q16, Alaska Air Group’s YoY capacity growth of 11.1% was slightly higher than the expected growth of 10.8%. The company expects capacity growth to slow down to 5% YoY for 2H16. This would take 2016’s growth to ~8% YoY.

Although this growth is slower than ALK’s 2015 growth, it’s still higher than the capacity growth guidance for its legacy peers American Airlines (AAL), Delta Air Lines (DAL), and United Continental Holdings (UAL).
