Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

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

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

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.

The entertainment and wifi mostly didn't work on this flight.

Boarding was tough as we had to take a bus out to the plane and walk up a lot of stairs. Difficult with heavy carry-ons that said I got an entire empty row of seats, which was excellent for an international flight. Food was very mediocre but happy with the comfort so not complaining.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.

Delta is better for short flights and very low need for customer service. Avoid for longer flights

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

All flight attendants could benefit by taking an international flight on Qantas Airline. Qantas attendants are much more hospitable in every way. Much superior than and attendants on any US airline.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

So far so good but food and entertainment are not available for this flight

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

The flight was 2 hour delayed, otherwise everything was excellent. The delay was due to the hourly limit requirement so given that as a reason, I'm happy with the flight!

Not sure the logic of the boarding in Groups. I was loaded first on the aisle. Then the guy in the middle. Then the guy by the window. Constantly holding up the other people boarding behind them with us blocking the aisle and this happened in most of the other rows

To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.

The plane was late and then sat on the runway for almost 45 minutes before taking off.

Crew professional. Easy bag drop off. On time. Good entertainment.

Everything was great. Boarding, early departure, early arrival, and deplaning were smooth. Smooth flight.

Per usual, flight status, staff courtesy and professionalism were excellent

Everything was on time, we arrived early, everything worked well.

The only thing is if Wi-Fi is available after you land and taxi to the gate. It takes forever to get to the gate, and having the Wi-Fi continue would be great to bide the time at least 5 minutes before you arrive at the entrance. That is my only comment; otherwise, everything was good.

Lots of overhead storage, good crew, good service, smooth landing.

Crew was friendly. Lost our luggage and told us it’d be in later in the evening of the day we returned. It was not. Still after 5 days have not received it.

It was good, flight was on time, boarding was smooth and done in zones, food was good too but there was no form of entertainment. Luggage’s were intact. So an overall good flight

crew was great, wifi was very poor could not even load a youtube video

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

First flight out in the morning is often the best chance of running on time. Not in this case, which unfortunately is now what passengers can expect as what is common. - If you are late for a flight, too bad for you. - If West Jet is late, too bad for you. - Bags don't make it? Too bad for you. - Flight change by 1+ days, too bad for you Prices continue to increase, while customer service nosedives. This is backwards and in any other develop country would be considered unacceptable - except for Canada. Too bad for us.

Experience was good. Was surprised they didn’t offer a complimentary meal on a 5 hour flight.

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

The flight attendants were great, but not much room while sitting and it would be nice to get free movies.

Original flight canceled and communicated poorly. A series of gate changes , delays and plane changes followed. Even after the entire flight boarded there was another plane changes followed. Food vouchers provided to my travel companion but not to me despite being on the same reservation. No in flight entertainment. The entire experience was terrible although the flight crew were great.

Like- beer/wine for free Dis-like- all other aspects- customer service was horrible the entire trip. No help from Air Canada after they changed flight 6+ hours later. Also they put us on standby for no reason. Then almost 2 hours to get our bags after we arrived back at airport

The plane in use lacked an entertainment system (perhaps because it was still being updated?). It was an overnight flight so it wasn't terrible but still. The actual seat was adequate but not great. As an economy flyer, food review is largely irrelevant. I am unhappy with this race to the bottom for services provided especially as it applies to baggage restrictions.

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

Ground personnel in better mood. Sounded agressive wrt carry on bagage sizing.

As usual, terrible. Delayed flight, missed connection and wasted hours at the airport. The only reason I use this airline is because of limited options.

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.

Everything was made rather simple, so I appreciate that. All the people I dealt with from entering the airport in Jacksonville to my lonnnnnnng walk to my next gate in Chicago were excellent and very helpful.

Terrible. 3 missed flights and 24 hours delayed with lost bag and promised $100 compensation from United and absolutely nothing from them…

The flight was delayed to 1:50 am from 12:05am which caused confusion for us on the connecting flight.

Not much....we did not get the complimentary beverages promised in our ticket. My partner and I did not have the window seats promised. We didnt get to sit together.....
