The food option was finished and what wa left was vegan pasta so I had to go without food for an 8 hour flight without any sort of empathy from crew that was mean.

Mediocre|Sept 2025

Crew and snacks were good, boarding wasn't great as busses were used rather than boarding tunnels. Also endured a one hour delay.
