Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

I appreciate the staff who allowed me to board though I arrived a little late! Regarding the assigned seating, I had booked my flight before this change and wasn't aware of the change at the time, and so I didn't select a seat at booking as I didn't realize it was relevant. Better communication about the change would have been helpful for preparing.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

WiFi on the flight was not working. Thus, entertainment options were limited.

Crew always seems to be unprofessional no matter what Southwest flight I fly

Southwest failed to leave on time forcing us to circle the airport due to weather. Please stick with the schedule and delays won't stack up.

The crew and everyone on board was wonderful, We had to wait for a flight attendant to come from Orlando to Jax after a sudden illness., We left an hour late and “missed “ our connection.flight. The plane was held for us but we were told that our bags probably wouldn’t make the flight even though we would and would have to return to the airport in Boston pick up our late luggage or choose to fly on the same flight as our luggage. We chose to wait 4 hours on the next flight with our luggage and missed our first day in Boston for our grand daughter’s 10th bday celebration. When we arrived on the next flight, our luggage was sitting in a room waiting on us - evidently it did make out original flight., We were given meal vouchers in Baltimore for our delay which we really appreciated and thought was a very kind gesture by Southwest - sudden illnesses are not their fault., I just feel like we would not have missed an entire day in Boston if you offered more early morning direct flights and /or had offered to deliver our luggage to the hotel instead of us having to return to the airport to retrieve our luggage on the next flight due to a technicality - it wasn't “lost luggage”. Other than that , it was a perfect flight .

We sat on the tarmac for 2 hours waiting in line to be de-iced. The flight is 1.5 hours, so we spent more time tied to our seats for no reason than actually flying.

Always dependable. No surprises. That’s how I like to fly!

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Aside from a completely packed plane, I really have no complaints.

The flight was very good and the staff was very friendly and helpful!

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The food is terrible. The staff is wonderful. Comfort is good.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

Excellent check-in. Crew was good. Excellent communication from flight deck.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

Flight was on time, the staff was personable & professional, & the plane arrived on time.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

The boarding process was straightforward. One pertinent observation regarding all boarding procedures is that if an individual requires assistance or possesses a special status and is part of preboarding, it is advisable to limit the number of passengers who can preboard with them, rather than the entire, sometimes large, companion groups. The seats are uncomfortable, and the entertainment options are significantly inferior compared to other airlines. During the snack service, I requested an additional bag of snacks, but my request was denied. Initially, the flight attendant agreed to my request.becoming a strange accurate moment. The flight duration was four hours.

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

I liked all the informational texts. I always knew where to go and when .

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average, Air canada food was much better than united.

They cancelled our flight at the last minute due to mechanical issues. Rather, they “delayed” it till the next morning. A pain in the neck when traveling with two young children. Crew was really nice, which made up for it somewhat. This is the second flight from delta that was cancelled this year. Definitely going to fly another airline when possible

Noticing spectacular about the flight. It got me fro m point a to b. High priced

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

The flight was fine. It's the satellite terminal that supports American eagle flights is what sucks. There is only one food option and everything there is way overpriced. I mean I know it's airport pricing, but it's even crazier than that. I bought a sandwich in a plastic container for $18.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

Delayed 4 hours from Charlotte to Nashville. Could have driven there faster. Information provided by AA was sparse.

Gate change was a little tough but it was a good flight otherwise

Great flight, great service but most of all- our luggage made the trip with us.,

Great except upon arrival it took them a long time to open the doors

It was awful ....my first time flying on it and I will NEVER fly it again ....everything about it was terrible .....most especially the flight attendants

It was an early flight and most people napped/slept and the crew let us which was nice.

The experience was good. No frills but I got there safe and sound and on time.

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

The seats were extremely hard and uncomfortable. It was disappointing even for a budget airline.

Frontier notifying me earlier of flight delay of over 2 hours.

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.

They lost my baggage on my connection flight, it’s been 24 hours since I put my claim in and still no update on my bags.

The flights were right on time. The issue that was the most difficult was the lack of legroom on the planes
