Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

No internet on a flight over three hours in this age is criminal. Staff inattentive and dismissive

The captain gave good announcements and the flight attendants were friendly. The WiFi was pretty good. The plane itself looked very old inside and the seats were very uncomfortable. The screens in the seat backs were the smallest I’ve ever seen. There were so many loud and obnoxious kids on this flight and the parents didn’t do much to try to quiet them down. Some had videos and games on tablets with higher than necessary volume going the whole time.

The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.

It would have been nice if they had offered more than one set of snacks

Excellent from start to finish. All staff members were amazing!

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Very well organized both boarding and deplaning. Very satisfied with the service I received.
