Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

From boarding to disembarking, the whole operation was very efficient.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It would be nice to have power to charge phone.

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

Crazy long boarding times, messy, inexperienced, overworked, and visibly tired crew, very uncomfortable seats and no compensation for delays.

I couldn’t understand the aircraft tannoy announcements I was in seat 20C - nobody in our row could either. Speakers a bit too quiet plus messages read out too fast. Otherwise excellent flight. (Flight delayed by 50 mins)
