JetBlue has begun placing its code on Aer Lingus flights.
The carriers are now codesharing on Aer Lingus-operated flights from New York and Boston to Dublin and Shannon. JetBlue also said it plans to codeshare on select Aer Lingus routes beyond Ireland in the near future.
The new codeshares expand upon the unilateral codeshare arrangement JetBlue and Aer Lingus have had since 2013. Aer Lingus already places its code on more than three dozen JetBlue flights out of Boston and New York.
