Flight was delayed 2.5 hours - a big deal on an overnight when you plan to sleep.

Flight was delayed 2.5 hours - a big deal on an overnight when you plan to sleep.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The ride was good but no food ot entertainment hence, it was just over an hour flight.

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

No snacks served! Seating in the kast row in uncomfortable.

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. Very comfortable business seats with nice bedding. Good food. We were delayed to let late passengers on the flight, but otherwise great experience.

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

This is not a Business Class equipped airplane and even the crew apologize before take over BUT BUT Air Canada charged full business class fare

All was good, except our baggage was lost for most of a day. We are thankful that it was found quickly and delivered to our hotel. Rouge was fine outside of that problem.

Easy boarding, roomy seats, plenty of good food, very helpful snd friendly staff. Very smooth flight! Only thing that could have been better was to have cranberry juice. Women like this as it helps avoid UTI’s and not as sweet as other juices.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

The late departure Of two hours waitresses, immature, and gossiping

It was upsetting that the flights were canceled but that was due to weather. I did not receive any vouchers for food or a hotel stay when I was forced to spend the night in Montreal. I was also upset when my seat was changed many times.. The plane seemed old with a non-functioning screen and loose side pockets.. All in all in need of updating. On the positive side, the staff in areas was friendly and helpful.

The flight got canceled multiple times and we had to drive their to reach midnight for our next morning interview. Poor and unriable experience. Now have to ask for a refund since we didn't need their rescheduled flight three days later.

I love flying with AC. I love that they have power outlet and free messaging wifi for aeroplan members.

Nice small trip, No food included in ticket, but beverages were for free.

All of our flights got delayed. Fll-Montreal delayed due to technical issues. We got transferred to a Fll-Toronto flight, in Toronto flight got delayed 5 hours causing us to miss our connection to Amman. We are now arriving to Amman 24hours later
