WINDSOR LOCKS -- Low-cost carrier Norwegian Air will stop its weekly flights between Bradley International Airport and Edinburgh, Scotland, citing delays in a Scottish tax break the airline expected.

The decision means Norwegian Air will completely pull out of Bradley. The flights began in June and will end March 25.

The decision leaves Aer Lingus service from Bradley to Dublin, Ireland, as the only transatlantic flights offered from Bradley.

"Whilst this route cut means that Norwegian will currently not be offering any service to/from Bradley International Airport, the airline is continuously reviewing other future opportunities in Hartford as we have seen great potential in this market," Norwegian said in a statement.

Passengers were notified Monday morning, told of alternate routes and offered refunds if they choose not to rebook flights with Norwegian, airline spokesman Anders Lindstrom said in an email.

Norwegian will continue serving Edinburgh from Stewart International Airport in Newbugh, New York, and from T.F. Green Airport near Providence, Lindstrom said.

After March, Norwegian will continue to serve 12 U.S. airports on various routes, including T.F. Green.

Norwegian at first offered three flights a week -- on Tuesday, Thursday and Saturday -- but switched to a Wednesday and Saturday schedule during the winter season.

Tickets were cheap, with fares beginning at $65, including taxes. The no-frills price does not include checked baggage or a meal, and allows for only a small carry-on item.

According to data kept by Bradley, 7,800 people flew Norwegian from June through November. November is the most recent month for which numbers are available.

Aer Lingus flew 39,000 people to and from Dublin in the first 11 months of 2017.

"We knew from the start that the lack of connecting options at Edinburgh Airport would make the Norwegian service a challenge to maintain. However, we were pleased to see that Norwegian's performance was in line with expectations for a new airline entrant starting operations at Bradley," said Kevin Dillon, executive director of the Connecticut Airport Authority in a written statement. "This unfortunately was not enough to mitigate the financial pressure that the airline has experienced on the UK side."
