Online check-in 24 hours in advance something seems not so easy to check in to pick seats and to print a boarding pass

Online check-in 24 hours in advance something seems not so easy to check in to pick seats and to print a boarding pass

I like the crew, very welcoming. Food can be better. The seat arms don’t go up so. I could use the empty seat next to mine to relax better. 3hrs delay 😠

They sat my 2 year old in the seat behind me, separate from myself and my 5 year-old daughter. When I asked them to fix it they told me to speak to the gate agent in London. When I asked in London they told me to talk to the cabin crew. Then a “Supervisor” stuck us in row 39 at the back of the plane when we were originally sitting in row 25/26. They ran out of food which was gross anyway, and the entertain didn’t work the first hour of the flight. Overall terrible experience.

Last minute charge for 1 checked luggage before boarding which wasn’t mentioned when we bought the tickets months ago. It was an unexpected surprise. We had no choice but to pay to board. Most airlines allow your first luggage free.

In-flight service was very good. The entertainment system keeps resetting, it happened at least 7 times.

Boarding was efficient and quick, crew was very attentive, seats were comfortable.

The crew was friendly and helpful. The food was terrible.

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours

Terrible service especially for premium economy. Much more comfortable seats on other providers

Friendly hosts/hostesses; dinner was of acceptable, but mediocre standard
