Months after launching the historic flights, some airlines are already cutting back.

Several airlines are cutting back on scheduled commercial flights between the U.S. and Cuba.

While travel from the states to the island nation has greatly increased, the rush to provide services has outpaced demand.

Frontier Airlines and Florida-based Silver Airways both announced that they will be ending all Cuba services this year due to increasing competition from other airlines, the Associated Press reported.

Silver Airways will be ending its Cuba service on April 22, just six months after launching routes between Fort Lauderdale and cities in Cuba including Camaguey and Cienfuegos. An airline spokesperson told AP that the number of available seats on flights between the U.S. and Cuba had quadrupled as more airlines added flights, and the increased competition made the route unprofitable.

“While the actual total number of passengers currently traveling to and from Cuba on all carriers combined is in line with what Silver originally projected, other airlines continue to serve this market with too many flights and oversized aircrafts, which has led to an increase in capacity of approximately 300% between the U.S. and Cuba,” Misty Pinson, a spokesperson for the airline, told Today in the Sky.

Meanwhile, Frontier will scrap its daily flights from Miami to Havana on June 4 due to heavy competition and unexpected costs for providing service at the Havana Airport, a spokesperson told AP.

Last November, American Airlines also announced that it would cut its daily service to Cuba by 25% and switch to smaller jets on several routes, while JetBlue announced it would begin using smaller planes to make up for a lack of demand on flights, according to Bloomberg.

Several other U.S.-based carriers, including United and Southwest, will continue offering their Cuba routes as scheduled.
