The US customer service team for Aer Lingus are absolutely awful.
Every one of them have no intimate knowledge of the inner workings of Aer Lingus or AerClub and have a horrible attitude on the phone, quite frankly I really hope this decision is reversed and the call centre was centred elsewhere.
However, I have found BA's new call centre reps in India to be polite and helpful - perhaps EI might make a similar move!
