Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Not consistent with the food quality (I mean taste not freshness)

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

All was very good however the breakfast was a bit tasteless on both flights. Many people seemed to say the same thing. Otherwise really good .

Is a terrible airline. The seats are tiny, staff are lazy and rude. Everything is a mission for them and they always take forever. Check in and passport control is enough to turn you off Mauritius all together. Let alone the airline. Mauritius is gorgeous and a must visit if you could avoid the airport and Air Mauritius.

Check in and passport and security time’s appalling Not enough staff for the volume of flights departing.

The crew were great as usual. The flight was rescheduled two hours later but delayed by more than an hours to load cargo. The was upsetting because I missed scheduled meetings in Johannesburg.

Though the food was very good ,I think the portions were too big. It was hard to manage everything on that small table. And you really don't feel like eating too much on a long flight. Just a suggestion and it would save you some money too.
