Friendly crew. One seat didn’t have a window and another no foot rest.

Friendly crew. One seat didn’t have a window and another no foot rest.

Free WiFi was much appreciated. The only choice for food being a pepperoni sandwich was disappointing.

Food can be more healthy instead of processed. Crew was friendly and courteous. Our flight time changed so they gave us extra comfort seats which was very nice.

Starlink is a big plus and great customer service - boarding agent and the flight attendants

Good service because of wheelchair. Tight seats. Some announcements were hard to hear or understand. No directions for working the seat video or meanings of the icons. Coming into the country and changing planes was terrible with long lines and few desks open at the end. I had to go through twice because they found my tiny knife with fingernail scissors and file, when they scanned my checked luggage, and in order to keep it. I had to go through that long line a second time. Going home the luggage was checked all the way through

Everyone great! Did not sitting behind the flight attendant jumpsuit. Nowhere to put my bag or feet.

Service was so slow. I didn't get enough food and drink.

The return flight was 1.5 hours behind. Also some passengers lost their luggage or was delayed.

Arrival was not good - waited on the tarmac after landing for nearly an hour

The food. It was nice having a meal provided, but I wasn't able to eat it.
