Puerto Rico and the United States are to become easier to travel between with Avelo Airlines’ historic new red-eye service from Tweed New Haven to San Juan. The inaugural overnight flight provides passengers with greater flexibility in terms of travel options, linking Connecticut with Puerto Rico in a manner that suits the preferences of early bird arrivals as well as those arriving later in the night. The new route is an important addition to Avelo’s network offering both regions greater connectivity and convenience while providing an efficient and affordable travel option for an ever-growing number of travelers.

Avelo Airlines, an ultra-low-cost carrier, is marking a significant milestone in its journey by launching its first-ever overnight flight, a red-eye service, on June 12, 2025. This marks a major shift for the carrier, which has focused on daytime services since its revenue-generating flight debuted in April 2021. While red-eye flights have long been a staple for other carriers due to their efficiency, Avelo had previously avoided them due to the additional crew requirements and operational complexity that come with nighttime services. However, this new route reflects the airline’s evolving strategy and commitment to expanding its service offerings.

Starting on June 12, Avelo will introduce its first overnight service between Tweed New Haven Airport (HVN) in Connecticut and San Juan, Puerto Rico. This new route will depart from Tweed New Haven at 20:59 and arrive in San Juan at 00:45 the following day. The return flight will leave San Juan at 02:42 and return to Tweed New Haven at 06:45. According to Cirium Diio data, this new red-eye flight marks Avelo’s fourth-longest route in its entire network, and it aligns with broader trends seen across the industry, as overnight flights from San Juan to the U.S. mainland have become common among major carriers. This expansion follows closely behind Southwest Airlines, which recently ramped up red-eye services to the East Coast.

Avelo’s First Overnight Flight: A Game Changer for the Carrier

The airline began offering service on the Tweed New Haven-San Juan route in November 2023, initially operating only daytime flights. However, with the addition of red-eye services, Avelo is tapping into a growing market for late-night and early-morning flights that cater to passengers looking to maximize their time at their destinations or connect to early flights from their arrival airports. This schedule shift reflects the airline’s ability to adapt to market demands and cater to travelers with different preferences.

On Thursdays and Sundays, a Boeing 737-800 with 189 seats will operate flight XP327, departing Tweed New Haven at 20:59 and arriving in San Juan at 00:45 the following day. The return service, XP328, is scheduled to leave San Juan at 02:42 on Fridays and Mondays, arriving in Tweed New Haven by 06:45. The remaining services on Wednesdays and Saturdays will continue to operate during the day as before. This new schedule not only opens up more flight options for travelers but also sets a new precedent for early arrivals at Tweed New Haven.

Earliest Arrival Yet at Tweed New Haven Airport

The early-morning arrival of flight XP328 at 06:45 is the earliest ever recorded for Tweed New Haven Airport. Historical flight data from Cirium Diio reveals that no scheduled service has arrived at or before this time in the past 20 years. The earliest flight arrival previously was at 07:00. The arrival of flight XP328 signifies a step forward for the airport, which has seen its infrastructure evolve over the years. This new early-morning service reflects not only Avelo’s growing presence but also the airport’s ongoing efforts to modernize and accommodate increasing passenger demand.

Tweed New Haven Airport’s history dates back to 2007 when Pan Am Clipper Connection, operated by Boston-Maine Airways, introduced service with 19-seat Jetstream 31 aircraft. These flights, which were primarily focused on business travel, operated thrice daily from Elmira and Portsmouth to Tweed New Haven, with the first flight of the day departing at 06:00 and arriving at 07:00. Fast forward to today, Avelo’s new red-eye flight represents a leap in both the carrier’s capabilities and the airport’s role in serving Connecticut and the surrounding areas.

Overnight Flights from San Juan to the U.S. Mainland

Avelo’s new service adds to the growing trend of overnight flights from San Juan to various U.S. mainland destinations. Industry data reveals that 6% of flights departing from San Juan to the U.S. mainland depart between 00:00 and 04:59, with airlines like American, Avelo, Delta, Frontier, JetBlue, Southwest, Spirit, Sun Country, and United all operating red-eye services. These overnight flights serve a variety of U.S. airports, making it easier for travelers to connect to destinations across the country.

As seen in the table, a variety of airlines are contributing to the growth of overnight service from Puerto Rico to major U.S. destinations, with Avelo’s flights fitting neatly into this pattern. By offering red-eye services, Avelo is catering to passengers who prioritize early arrivals at their destinations or require convenient late-night flights for connecting to other routes.

Expanding Avelo’s Reach

Avelo Airlines continues to expand its reach, offering more flexible travel options for passengers across its growing network. The carrier’s introduction of red-eye flights is just one example of how it is meeting the needs of its customers by offering affordable, convenient, and strategic flight options. The Tweed New Haven to San Juan overnight flight is a significant milestone in Avelo’s expansion and signals the airline’s ability to adapt to the changing demands of the travel industry. As the airline moves forward, it will continue to explore new opportunities to grow its network and serve passengers with even more travel options.

The United States and Puerto Rico are enhancing travel links with Avelo’s inaugural red-eye flight between Tweed New Haven and San Juan. The new overnight service provides increased flexibility, improving connectivity between the two territories.

Avelo’s shift to include red-eye services further establishes its competitive edge in the ultra-low-cost carrier market, giving it the ability to compete on a broader scale with both legacy and low-cost carriers. The airline’s dedication to expanding its routes and service offerings reflects its broader goal of connecting travelers to key destinations across the U.S. and beyond, with a focus on providing value and convenience.
