Norwegian has announced several transatlantic frequency increases from Dublin, Edinburgh and Shannon airport for this winter.

The carrier recently dropped selected services to Providence and Stewart International this winter, and the freed up aircraft are being used to bolster more successful routes over the period.

At Dublin airport Norwegian will continue its increased summer schedules to New York’s Stewart International (double daily) and Providence (daily) into the winter season, while at Shannon it will increase winter frequencies on its Stewart International route from two flights per week to daily.

Meanwhile at Edinburgh the carrier will maintain daily flights to Stewart International over the winter period (up from three flights per week last year).

Norwegian says the increases will add 90,000 seats to the USA this winter, with CCO Thomas Ramdhal saying that the changes “focus on boosting services that reflect strong passenger demand”.

Last week British Airways’ parent company IAG confirmed it had taken a minority stake in Norwegian, in a move which could eventually lead to a full offer for the airline.
