Skinner, Aug 2026

The whole staff was very very accommodating and helpful. I have a broken foot right now and they helped me out the whole way to Tampa Bay. Leg room is always an issue but the staff was amazing

4.0 Mediocre

Jonathan, Jul 2026

Please bring back hot meals on long flights. Or at least something besides crackers and other starchy stuff. Maybe fresh fruit. I would be willing to pay higher fares for this. Also, whatever happened to wide body jets on transcon or Hawaii flights. A five hour flight on a single aisle plane is not comfortable.

6.0 Okay

Mendy, Jul 2026

Old airplane, crew forgot to bring me my kosher meal, and I had to ask for it twice, and wait until everyone finished receiving their meal, drink, and garbage collection, and then they brought me mine.
