We had the pleasure of meeting cabin service manager Paul He was very attentive as we were flying to NY for my daughter shaunas 21st present. He was very chatty and made r flight even better. Overall staff were very friendly 😀

Killian, one of the air hosts, was the best I've come across. His two colleagues on board were perfect and even still, he stood out.
