The crew was very helpful and friendly.

The seats were too compact. No snacks no seat selection without some form of payment.. extremely turbulent flight.

One crew members was basically screaming the entire flight. It was a late flight and I literally know her entire life and what she eats everyday! So Rude

8.0

Very good|Nov 2021

how does the flight attendants not say anything when people are not wearing their masks at all - people were getting on the flight with no mask. People were not wearing it at all during the flight. It makes things really uncomfortable and puts everyone at risk.
