Airline reviews

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

Boarding was confusing with a delayed flight because there was no English translation

We didn’t have any entertainment. I tried to go online without success. The airplane was extremely cold and they didn’t have blankets.

Only complaint is that the entertainment system wasn’t working on our seats and some others.

The Flight was delayed in 2,5 hours. 1 hour inside the airplane then we passangers were not allowed to receive food as the local regulariam determines (for delays bigger than 2 hours)

For bus boarding, group 1 should have been sent on a separate bus ahead of the general boarding. It would have been nice.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

It was ok for the most part, it is missing something

Liked check in process To improve: food and beverages. Not second round was offered and meal had no salad.
