Wes, Apr 2026

All the amenities was wonderful, if they could keep their prices that low. I'd fly with them all the time.

6.0 Okay

Carlos, Apr 2026

Very old plane with no inflight entertainment. I purchased the internet pass and it was nearly unusable.

4.0 Mediocre

Lisa, Apr 2026

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

8.0 Very good

Mary, Apr 2026

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

2.0 Poor

Grace, Apr 2026

My flight yesterday evening was delayed 3.5 hours with no water or food service. Poor experience

10.0 Wonderful

Aditi Sayan, Apr 2026

Transparency from pilots, quick boarding and exiting the plane, staff greeted to each and everyone,

4.0 Mediocre

Jeffrey, Apr 2026

Didn't like sitting on the waiting pad for 30 minutes right after departing the gate. If you're going to do that, just don't board so people can still get up and walk around in the terminal. My luggage was damaged by the baggage handlers.

2.0 Poor

Leslie, Apr 2026

Pilots lied about waiting on “paperwork”. Sat in the plane for over an hour, waiting on some papers to be printed according to the pilot and then all of a sudden he says good news maintenance is finally on their way. Maybe they can fix it before we get our paperwork. Ended up missing my connection in LaGuardia and as a result, had a fly home to Lexington instead of the Louisville airport. Then paid $100 to uber to Louisville since it was midnight by the time I got in. I wish they would just be transparent with passengers sometimes and not try to beat around the bush on why things are delayed.

2.0 Poor

Gregory, Apr 2026

The WiFi was horrific. I fly delta often and love their (usually reliable and free) WiFi. On this flight it was intermittent and when it did connect was extremely slow. I couldn’t get any work done while I was on the flight which was extremely frustrating. I was also in the exit row seat where there is now immediate seat in front of you, so while the leg room was nice, I couldn’t even watch the TV when the internet wasn’t working. Finally, for the last 20 mins of the flight, the announcement indicator came on the TV screens and took them over, even though no announcement was being made. Really disappointed.
