On July 18, 2026, nearly 4,900 flights were delayed and 126 canceled across U.S. airports including Chicago O’Hare and JFK. FAA staffing shortages and Canadian wildfire smoke reduced visibility, exacerbating disruptions.
Frontier Airlines announced four new routes launching later in 2026, adding service to Denver, Detroit, Fort Lauderdale, Houston, and San Juan. Special fares start at $69 for non-stop travel through January 4, 2027.
