Seats were uncomfortable, you could barely see the screens with the poor quality , really bad selection of entertainment for example they might have one or two episodes of a programme not the complete set like other airlines which were far superior In comfort and entertainment. The staff were excellent and this made up for it

Yes I was very annoyed that we were made to pay an extra €85 to check in our luggage all the way to Vancouver, when I already paid €854 for the flight. I have never been asked to pay for check in luggage on a long haul and if rules have changed we should have been notified clearly and respectfully. My colleague and I will be taking this up with expeadia! €85 is one way by the way so we have to pay another sum on our return.

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.

Mobile check-in experience was bad! Confusing and time consuming when compared with many other airlines I very regularly fly with.
