The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Wifi wasn't working on one of the UA flights after boarding.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Unfortunately this is not a happy ending comment. Positive: flown United before no issue Negative: it only takes one bad experience to not plan future travel with United Cancún departure was delayed by 1h20 minutes, connection in Chicago was 1h30 minutes. Flight departure time 6:08 Miraculously 7 of us ran 4 kilometres through Chicago to arrive at 6:00 to be told very rudely by the 2 unprofessional United attendants you missed your flight and that we should of arrived early. Did I mention that reason I was flying? I received a call that my brother was dying and to get home. They provided no assistance would not answer any of our questions, ignorantly walked away. Deplorable

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

If United expects people to use their own devices for entertainment they should put charging outlets in each seating area. I arrived with 14%battery power. That is not good when you arrive anywhere and need to communicate for transportation.

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

The flight got canceled due to mechanical issues, and he to be rebooked and missed my appointments for that day

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Service and food are good. However, main cabin with the extra cost one pays could be better. I don't see any difference with the rest of the seats in the regular category. The seats are too close to the ones in front. For short flights it is Ok, but for long ones there should be more space.

As with every airline the seats are not built for tall people.

Flight was delayed by well over an hour. Communication was terrible.

Fast check in, easy to navigate, crew were very good, the plane was delayed due to a previous flight and I found the cleanliness a little lacking but overall it was fine

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

Seats, comfort level ugh. Crew was not attentive, only to coach

All corners have been cut and it’s a cheap experience that no longer is distinguished from most other cheap airlines

Pros: they tried to accommodate bc they forgot my gluten free meal Negatives: The flight was freeeeeezing Iberia didn’t communicate my gluten free meal

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.
