Crew was amazing, boarding was simple and quick, only issue was the food. I was flying first class, and while it was only a two hour flight, the food really could have been better. I got the "protein plate", which was a few pieces of chicken (kinda dry), some sliced cucumber, feta cheese, and literally a whole unpeeled carrot just plunked down. Again, I know the flight was only two hours, but for what we paid for first class I was kinda hoping for a bit more than something that belongs in a cheap airport cafeteria. Other than that, the flight was great; comfortable seats, great service, great crew.
