The reps working at the airport counter were dumber than a second coat of paint.

Anonymous, Apr 2025

My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks

6.0 Okay

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

2.0 Poor

Anonymous, Apr 2025

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.
