It was great honestly the cabin crew were warm and welcoming everything was perfect the food was nice.

It is almost 7 hours journey ,you should have provided with TV entertainment and mobile charging

It’s very tiring journey with only 3 seats in a row and not good for family of four. Online checkin don’t work and unable to select the seats while going.

Ok, the flight was not full yet I had people on both sided and the chairs were tight. Only 2 kinds of snacks didn’t even have milk for the coffee.

Make all food options available, than running out even before mid way through the service

I wonder why checking carry on bags while the checking process was done by Moroccan security. Is it question of trust or Morocco security system is not qualified enough?

Much better than our first flight. Perhaps healthier food options and more food.

The check in process was a disaster. There no clear lines and there were people everywhere, pushing and cutting in line. There was no communication about flight delay and our flight arrived 5 hours late. Causing us to run to our next flight. Our luggage did not make the flight

Behaviour of the staff very unprofessional. Choice of accepting Tea and coffee was only at the time of recieving meal. I requested if I can have tea later. Response I got was" I am going to sleep after serving food, either take it or will not be served letter". Few hours later I saw many passengers getting to kitchen and getting a cup of tea.
