Amber, May 2026

The planes were full to the brim! I understand that is how they make their money, there was no room for my backpack overhead and got the great pleasure of bumping into and rubbing my butt on at least 9 arms. Other than that, the flight attendant let me get some much needed sleep.

One of the best costumers service ever!!!

4.0 Mediocre

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.
