International Service at JAX
Jacksonville International Airport is primarily a domestic airport, but it does offer a small amount of international service. Air Canada operates seasonal nonstop flights to Toronto, running roughly June through October. Puerto Rico is also reachable nonstop, with both JetBlue and Frontier Airlines flying to San Juan. There is currently no year-round scheduled service to Europe, Latin America, or the Bahamas from JAX, so travelers headed to those regions typically connect through a larger hub such as Atlanta, Miami, or Charlotte.
Amenities and Services Offered by Airlines at JAX
Airlines at JAX have invested in passenger experience over the past several years. Priority boarding is widely available for elite frequent flyers and passengers who pay for expedited boarding. In-flight service varies by carrier: full-service airlines like American, Delta, and United typically offer complimentary snacks and beverages on short flights, with meal service on longer routes, while ultra-low-cost carriers like Allegiant, Avelo, and Frontier charge separately for most onboard extras. Wi-Fi is available on most mainline aircraft serving JAX, and Delta operates a Sky Club lounge on Concourse A for eligible passengers.
Pro Tip: If you want lounge access at JAX, Delta’s Sky Club on Concourse A is currently the only dedicated airline lounge; check your airline or credit card benefits before assuming lounge access is available for your flight.
Tips for Navigating JAX Airport
JAX operates from a single passenger terminal split across two concourses — A and C — connected by a central mezzanine with shops, restaurants, and the security checkpoint. Arrive at least two hours before domestic departures and three hours before international flights to allow time for check-in and security. The terminal layout is compact and straightforward compared to larger hub airports, so travelers generally don’t need much buffer time to walk between check-in and their gate once through security.
Note: JAX has pet relief areas both outside baggage claim near bag belt 8 and post-security near the food court between Concourses A and C.
Dining options range from quick-service spots to sit-down restaurants, including Chili’s and Shula’s Bar & Grill on Concourse A. Travelers with TSA PreCheck or a Trusted Traveler program membership such as Global Entry, SENTRI, or NEXUS can use expedited screening lanes throughout the terminal.
Future Developments and Expansion Plans for JAX Airport
Jacksonville International Airport broke ground on a new Concourse B in May 2024, which will add six gates with room to expand by up to ten more. The Jacksonville Aviation Authority expects Concourse B to be completed by the end of 2026, positioning the airport for continued growth in both passenger traffic and airline route additions in the years ahead.
