Anonymous, Apr 2026

The flight was on an Embraer 175. Boarding was in time and we even took off on time. Being a regional Jet, there was no food in Business Class despite the fact it was a flight over 2 hours.

8.0 Very Good

Kosi!, Mar 2026

There was no screen for the inflight entertainment. Also, I volunteered to board a later flight in exchange for $300 credit, and they told me that I would receive the credit regardless of whether they needed me to board the later flight. However, I have not heard anything about receiving the credit.
