JetBlue Airways
is a major contender in the Caribbean
with several thousand flights each month. The airline connects the region from destinations along the East Coast, including its mainstay in New York. With Mint service on some routes, the carrier can set itself apart from other competitors as it is often the only airline to offer lie-flat seats unless another airline utilizes a widebody. JetBlue has not lost its grip in the Caribbean, as other carriers have sparked interest in the region in response to growing demand.
In the fiscal year ending 2023, US airlines collectively increased their seating capacity by nearly one million seats to Caribbean destinations. It came as demand
in several other regions appeared to plateau after a dramatic and extended surge following the ease of pandemic-related restrictions. JetBlue, however, has had to make some route cuts in an effort to save money. Despite reducing its seat capacity, the airline still has quite a presence in the region.
Here are JetBlue’s top five most-served Caribbean routes this month:
1
Orlando – San Juan
359 flights
According to aviation data and analytics provider Cirium, the most popular route JetBlue will operate this month is between Orlando International Airport (MCO)
and Luis Muñoz Marín International Airport (SJU)
in San Juan, Puerto Rico. The carrier has nearly 360 flights scheduled on the route, which covers an average distance of 1,189 miles.

JetBlue’s non-Mint equipped A321s will be deployed between MCO and SJU. Nonetheless, the A320 will handle the majority of the frequencies. The route is especially popular considering JetBlue competes with two ultra-low-cost carriers (ULCCs) and one low-cost carrier (LCC). Frontier Airlines
, Spirit Airlines
, and 
Southwest Airlines
all offer service on the route. However, JetBlue will operate the most frequencies.
