Which new routes are worth booking, and which are risky?

The latest round of route news is a mixed bag. United is adding four regional routes from Newark starting September 24 — to Charlottesville, Knoxville, Bentonville, and Omaha — all on regional jets. These are low-risk additions from a major hub, so if you live near those cities, they are worth booking. Alaska is also adding two new nonstops to Honolulu from Boise (daily from December 17) and Spokane (weekly from December 19). These are seasonal winter routes, but they eliminate a connection, which is a real win for travelers in those cities.

On the other hand, Aer Lingus is cutting routes from Minneapolis, Denver, and Las Vegas to Dublin by late 2026, citing low load factors and pressure from Delta in Minneapolis. JetBlue is dropping Daytona Beach and Antigua entirely, plus cutting four other routes, as it shifts resources to Fort Lauderdale. Frontier is adding four routes — including Denver–Fort Lauderdale and Detroit–Los Angeles — that were previously flown by the now-defunct Spirit Airlines. These Frontier additions are a gamble: the routes failed once under Spirit, and Frontier is a different airline but faces similar cost pressures.

What should you do? For new routes from strong hubs (United from Newark, Alaska from Boise/Spokane), book with confidence — they are likely to stick. For routes that are replacing a failed competitor (Frontier’s new Spirit-era routes), wait a few months to see if they survive. For any route that is seasonal or from a carrier in cost-cutting mode (Aer Lingus, JetBlue), book only if you have flexibility; if the route is cut, you will be rebooked or refunded, but your plans could be disrupted.
