First reported by IshrionAviation on Twitter, Icelandair has decided to add additional capacity to the United States for 2024, some of which to cities that the airline hasn’t even been operating for a full month.
Two northeast airports, Newark, and JFK Airport in New York City will both be seeing some significant increases in capacity. Newark will be switching from a Boeing 757-300 to a Boeing 767-300, going from a capacity of 216 per flight to nearly 260 passengers per flight between the airline’s Economy and Saga Premium class.
Service to JFK will go from 17 to 21 weekly flights, making an even three daily flights, versus only one currently on some days. These flights will be on a mix of 737 MAX, 757, and 767 aircraft.

Raleigh, N.C., one of the airline’s newer destinations, will also be getting a capacity increase from five to six weekly flights. This brings the weekly capacity of the route up by roughly 160 passengers.
Adding capacity in the Midwest
The final capacity increase is to Detroit, a route that hasn’t even been operating for a full month yet as it began on May 18, 2023. It will be seeing the same capacity increase as Raleigh going from five to six weekly flights.

All of these changes will be put into effect in the Spring of 2024.
