I have just checked with both SEN and Flybe, it appears to be 12 flights a week to DUB for the winter, although the SEN spokesperson seemed rather unsure and
Suggested it was all very new and speak to the airline. Flybe confirmed 12 flights
My concern which Flybe seemed unable to answer was whether they will be able to offer the same US immigration clearance facility in DUB that Aer Lingus Regional/ Mainline offer at the moment. This has been a good selling point from SEN. Time will tell.
