JAC Up 15%

Jackson, Wyoming, has introduced three new routes this winter: Charlotte; San Diego; and San Jose.
New York JFK was cut, so this winter it has 15 routes, up 15% year-on-year. 15 routes is its highest to date.
Charlotte, San Diego, and San Jose were all introduced in December 2020:

• Charlotte is served once-weekly by American using A319s
• San Diego is currently four-weekly with Alaska Airlines but rises to five-weekly from March
• San Jose, also with Alaska Airlines, is twice-weekly

Alaska is a new airline at Jackson this winter. Along with its two new routes, both previously unserved, it also launched Seattle. This is currently four-weekly and increases by one come February.
The carrier’s service to Seattle follows Delta ending it; it operated it from 2013 to 2020. It was served once-weekly using Embraer 175s; Alaska’s frequency increase is therefore notable.
These new routes – and crucially multiple capacity increases on existing routes – pushed Jackson’s seats up by 27% YOY to 562,000.
