Ten Aer Lingus flights were cancelled between Britain and Ireland on the 25th and 26th of September due to an air traffic control problem in the United Kingdom.
Nine of the flights were scheduled for the 25th and one on the morning of the 26th. Aer Lingus officials say that over 1,300 passengers were affected by the cancellations.
A spokesman for Ryanair was unable to say how many of their customers were affected by the problem.
The fault was pinpointed to Swanwick Control Centre in Hampshire. The problem was resolved after 3 hours. The fault affected planes coming into and leaving Britain.
Long delays occurred on manyroutes including Dublin to Heathrow, Dublin to Krakow, Dublin to Amsterdam and Dublin to Majorca Airport.
Aer Lingus and Ryanair both apologised for any inconvenience caused.
