They don’t give information on why a flight is delayed in a timely manner. Very frustrating.

They don’t give information on why a flight is delayed in a timely manner. Very frustrating.

The flight was ok but chargers did not work and the speakers in the back of the cabin did not either. But I am writing because the crew was really, really rude and not only rude but had the curtains always closed, forgot to clear our trays, the bathrooms were filthy and trash was building out, and one of the attendants even had her EARBUDS on while in the cabin. From movement it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. when we deplaned the crew in the back was just chatting with one another and the first class attendant was briefly and said goodnight. It is nice that a crew gets along so well, but they did not take care of passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller but I thought you really needed to know. Thank you, Carin

Food was terrible. They ran out of options and gave me a bland undercooked pasta and veggies. Only middle seat was available to select although I paid extra. Baggage delayed at destination. Flight attendants not really helpful.

Flight was late arriving. So, we left 25 min late. Pilot made some time up during the flight. Therefore, we arrived alittle past original time.

Crew was great. But my flight was late arriving and as a result, I missed my connecting flight to Richmond. I had to catch a later flight. On a positive note, the attendants at the counter were extremely helpful in booking my later flight. They book my on the next flight to Richmond.

If the plain wait for the passenger it should wait for the baggage!!

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

One one boarding scanner was working to scan 400+ passengers to an Airbus 380. Food in premium economy was mediocre.

Liked the flight being almost on time (airport issues created a delay). Disliked the issue printing tag bags on the kiosk and having to wait for an hour on like to drop my bags.

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

The staff was very good, the only thing was the air conditioning wasn't working during the boarding process so it was very hot inside the plane until we got airborne. The food wasn't great, the chicken was dry and hard to cut, the ravioli was ok and the little pizza pocket thing was pretty bad. Other than that is was a good flight all around

Everything. Boarding, service, food, seats, crew I'd increase the air pressure to avoid dry sinuses and after effects

Flight bumpy and aircraft old with tape over seats , it seems there is a lack of maintenance, air pipe blow off in the middle of the flight, flight attendant seemed not to be worried about it. Food got very bad over time , not only for the quality but for the quantity . Seats are very uncomfortable , entertainment not working properly.

The crew were great and constantly cleaning bathrooms and taking care of passengers. Flight was on time and arrived on time. Boarding was easy and hassle free. Food could have been better but decent selection. Overall recommend and will fly again.

Everything was good except the bathrooms were usually dirty and the trash bins in the bathrooms were full.

Better consideration for families traveling with a disabled person. They insisted each person hold their own boarding pass on their own devices and gave us a hard time accepting eight boarding passes on a single device.

At least it was a direct flight, however the boarding process was a nightmare. 2+ hours in line to check my bag. Then told it was overbooked and I have to go standby even though I bought my ticket months ago. Then sent to another line to get on standby - another long wait and finally started yelling that my flight was boarding. They sent me somewhere else. In the end I did make the flight - among the last group to board, even though I arrived 4 hours early at the airport. Worst check in process I've ever experienced in 50 years off flying.

Great crew, newer plane, boarding was very disorganized, I still don’t understand why airline keep boarding front to back for coach instead of back to front

Paid for a seat I didn’t get. Flight attendant said they would “report “ the problem. Food terrible. No service unless requested. Plane filthy. Seats falling apart. Broken footrest. Bathroom toilet held in place with tape. No gate announcements though delayed 2 hours. Is that enough?

I don't like anything in this flight the food was bad the service was bad the flight was old and not connected to the screen no intertainments at all and it was long trip was bad intertainments the crew not helping
