A738

Departing seat capacity across all airports in North America (Canada, Mexico and the US) is expected to grow by just over 10% in the second quarter of this year. Some 900 airports in the region will see departing seat capacity rise from 315.2 million in April to June 2022 to 348.3 million during the same period in 2023. That’s an increase of 33.1 million departing seats.

Over 21% of those additional seats will be provided by Southwest, with United and Delta both accounting for just over 14% each. In other words, just three carriers (out of almost 200) will be responsible for almost half of all the additional seat capacity added in North America during the last year.

The top 20 airlines for capacity increases in North America comprise 10 US carriers, five Canadian carriers (shown in red), three Mexican carriers (shown in green) and two non-North American carriers, British Airways and EVA Air from Taiwan.

Among the US carriers are the two new relative newcomers, Avelo and Breeze. However, notable by its absence is normally fast-growing Allegiant. Its capacity in the second quarter is down 1.1% compared with last year, according to analysis of Cirium schedules data.
