The ultra-low-cost carrier will begin service to La Crosse, Wisconsin; Philadelphia; Trenton, New Jersey; and Columbia, Missouri in the first half of 2026. All of these cities are brand-new to Allegiant’s network, except for Trenton, which was last served in 2018, per Cirium Diio schedule data.
“We’re thrilled to continue Allegiant’s growth by adding these new routes,” said Drew Wells, Allegiant’s chief commercial officer, in a news release. “Our mission has always been to connect travelers to world-class destinations at an affordable price. These additions provide convenient options for leisure travelers and reflect our commitment to expanding service where demand is strong.”
