Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

Crew was enthusiastic. Meal was surprisingly good. They came to give water very frequently. Negative that the seat reclining didn't work

This was absolutely one of the worst experiences of my life. I came to Europe for a 2 week trip and the airline was probably the most disorganized airline I’ve ever seen in my life. They lost my luggage. I had tracking on it for just such an occasion and told them EXACTLY where it was in the terminal and they somehow failed to get it out on the flight that night, since we were leaving for Switzerland the next day there was no way they would get it to our hotel in time. Seriously, take another airline at any cost. It’s not worth whatever you pay…you’ll end up paying a lot more in the end. My medication is in the bag and I can’t get to it and don’t know how I will get it.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

I have traveled to probably over a hundred locations worldwide, but had only one mixup of airport in Shanghai. Until Iceland and Stockholm. Reykjavik has 2 airports, Stockholm 4 (!). Please indicate clearly when a departure flight is scheduled from an aiport other than the international aiport. That would greatly reduce stress. Thanks

There is nothing Royal about Royal Air Maroc. Old planes, poor service, no entertainment and everyone of my 4 flights was late.

Intersting crew: only men with a bit of roughness. The food was not bad, but there´s no alcohol option

When the flight landed, it was still going towards the gate, when everybody got up. Nobody cared that the flight was still in "active taxi" mode. But seems like this is common on Air Maroc flights.

Seats were very uncomfortable (tight and hard). Flight was delayed due to technical problems. Baggage took an hour to arrive to the carousel.

While I had a business class ticket I wasn’t given priority to boar. Again my luggage had priority tags and these bags didn’t come out till the end!! The food at the lounge was only two type of sandwiches and warm juices and soft drinks I thought I’m paying for good services but the least u can say it’s mediocre at best. I’m considering not to use TAM AGAIN.

The service was terrible. We weren’t allowed to take water on the flight and the drinks were offered only at the end of the meal. When we used the button to call the flight attendants, they never showed up and when my daughter’s drink was spilled due to turbulences, she asked for something to clean her pants at least 4 times and eventually they gave her a tissue. The flight attendants were rude and overall the flight was terrible!

Good but your male staff should be more appreciative of customers. After all you are making a lot of monies from Nigerians.

I spent 4 hours untill get my bags no food no entertainment on the flight

Everything could have been better. Check-in was the worst. Staff was extremely slow for checking in. They were easily spending 10-15 minutes for every passenger. I almost missed my flight because there was huge line at Immigration also.

Pros: "It got us to Casablanca. Should have taken a car though"
Cons: "The plane sat on the runway at over 100 F and the A/C was not on. They barely started it once we were in the air"
