Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

Legroom in Economy was fair to good. Seat was omay; I was hit in the shoulder twice by the cart as it was being whisked through the aisle. Overhead space was good for my carryon. Lighting environment was nice

We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.

Raleigh to Chicago was OK. The problem was Chicago to Lincoln. Flight was delayed 4 hours. Give them credit for the updates and reason why it was delayed

Comfortable seats and good crew. There should be some breakfast options in menu for economy class to purchase Wifi was not working in the flight

On time. Accommodated carry on and personal bag in the plane. Good entertainment available and access without using own device. Gave a whole can of juice rather than a pour. Seat did not recline much.

Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.

The price. Omg $1100. Was crazy and it was not clear on the website.
