U.S. travelers have more options than ever for both domestic and international flights as American Airlines and Spirit Airlines announce major expansions. While American Airlines is increasing its global network with new routes to Cancun, Punta Cana, Hawaii, and Europe, Spirit Airlines is making a comeback at Raleigh-Durham International Airport (RDU) with five new domestic routes. These expansions provide more flexibility, whether you're planning a warm-weather escape, a ski trip, or a weekend city break.

American Airlines Expands International Service for Winter Travelers

American Airlines is making it easier to plan winter getaways with new and expanded flights to Mexico, the Caribbean, South America, and Europe. The airline will be the first to launch international service from Oklahoma City (OKC) to Cancun (CUN), starting Nov. 8, 2025. Additionally, American will introduce four new routes from Indianapolis, Nashville, Pittsburgh, and Raleigh-Durham (RDU) to Punta Cana (PUJ) beginning Dec. 6, 2025.

With over 270 peak daily departures to Mexico, the Caribbean, and Latin America, American Airlines remains the leading U.S. carrier for beach destinations.

For travelers seeking adventure beyond the beach, American Airlines is increasing flights to Hawaii, including resuming service to Kona (KOA) and adding a second daily flight to Kahului (OGG) from Dallas-Fort Worth (DFW). These flights feature premium cabins with lie-flat seats, expanded in-flight entertainment, and upgraded dining inspired by Hawaiian flavors.

Travelers heading to South America will benefit from four daily flights between Miami (MIA) and Buenos Aires (EZE) during the holiday season, as well as an expanded service between DFW and São Paulo (GRU), increasing capacity by 40%.

Meanwhile, European travelers can now enjoy extended seasonal routes to Athens, Barcelona, and Dublin beyond the summer months, allowing for off-season vacations with fewer crowds and unique seasonal experiences.

“American’s comprehensive global network is designed to give customers more access to the destinations they want to visit,” said Brian Znotins, American’s Senior Vice President of Network Planning. “Together with new routes, more flights on popular routes and extended seasons to major destinations, American’s schedule is designed for travelers to get away to sun, sand and more next winter.”

Spirit Airlines Returns to RDU with Five New Domestic Routes

While American Airlines is strengthening international service, Spirit Airlines is re-establishing itself in Raleigh-Durham (RDU) with five new domestic routes. Starting May 8-9, 2025, Spirit will offer nonstop flights to Baltimore (BWI), Dallas (DFW), Detroit (DTW), Newark (EWR), and New Orleans (MSY).

This expansion comes after Spirit emerged from bankruptcy protection earlier this month, following financial struggles and a failed merger with JetBlue. The airline, known for its budget-friendly fares, previously cut back service at RDU, maintaining only a single route to Fort Lauderdale. With this relaunch, Spirit is looking to reclaim its place as a low-cost leader in the Triangle region.

What This Means for Travelers

With both American Airlines and Spirit Airlines expanding their services, U.S. travelers now have more choices than ever, whether they’re looking for luxury, affordability, or convenience.

For international travelers, American Airlines’ expanded network provides more direct routes, upgraded in-flight experiences, and easier access to vacation hotspots.

For budget-conscious domestic travelers, Spirit Airlines’ return to RDU means cheaper flights to key U.S. cities, though additional fees for baggage and seat selection should be factored into travel plans.

Tips for Travelers Booking Flights with American and Spirit Airlines

For American Airlines Travelers:

• Book Early for the Best Deals: Popular routes, especially to Cancun, Punta Cana, and Hawaii, will sell out fast for peak winter travel.
• Consider Premium Cabins for Long Flights: American Airlines offers lie-flat seats and premium dining on long-haul flights to Hawaii, South America, and Europe.
• Maximize AAdvantage Rewards: Frequent flyers should sign up for the AAdvantage loyalty program to earn miles and perks for future trips.
• Check Baggage Fees and Policies: American allows a carry-on and personal item for free, but baggage fees vary for international flights.

For Spirit Airlines Travelers:

• Expect Low Fares with Additional Fees: Spirit’s base fares are cheap, but be prepared for extra charges on carry-ons, checked bags, and seat selection.
• Pack Smart to Save Money: Spirit allows one free personal item—a backpack that fits under the seat—while larger bags come with extra fees.
• Arrive Early for Check-In: Spirit’s budget model means longer lines at check-in and baggage drop, so arriving at least two hours early is recommended.
• Watch for Flash Sales: Spirit often offers last-minute fare discounts. Subscribing to their alerts can help travelers snag the best deals.

More Destinations, Better Deals: A Win for U.S. Travelers

With these expansions, U.S. travelers have more choices for winter vacations, business trips, and weekend getaways. Whether you’re looking for a luxury escape to Cancun, an off-season European adventure, or an affordable flight from RDU to a major U.S. city, these new routes make travel easier and more convenient.

As booking opens for these flights, travelers are encouraged to plan ahead, take advantage of loyalty programs, and compare costs to find the best options for their trips.
