⭐ Absolutely AWFUL Experience with United Airlines! If I could give United Airlines ZERO stars, I would. The seats have practically NO legroom, making the flight feel like being crammed into a tin can with nowhere to move. Comfort? Forget about it! And the fees? Absolutely ridiculous! They seem to charge you for EVERYTHING. You pay for your ticket, then get hit with extra charges for things that should be part of a decent flying experience. What’s next, charging passengers for breathing? Flying with United feels less like being a valued customer and more like being a walking wallet. The seats are uncomfortable, the legroom is pathetic, and the constant nickel-and-diming is infuriating. For the price you pay, you would think they could at least provide a little space to stretch your legs and a travel experience that doesn’t leave you feeling ripped off. Do yourself a favor and look at other airlines before booking with United. I certainly won’t be rushing to fly with them again. Absolutely disappointing from start to finish!

Flight was very smooth from Boston. But when we got to Houston, the gate was not open and we waited on the runway for over 30 min!!

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

Great, except the canon was so cold. Even the flight attendants put jackets on

The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying

The pre-order only approach for fresh food is really challenging

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

Lounge poor. Food poor. Airline service just ok. Business class seat not comfortable.

Business class seats were harder than expected, and lie flat we're not very comfortable. Less expensive than other business class flights, and much better than flying economy. The crew was excellent, as was the food.

This was one of the worst flights I have ever taken in my entire life. First of all, I traveled Economy, but the seats were TINY and cramped. Not just for me; everyone around me was complaining of the same thing and said they could not get comfortable. Then there was the issue of the heat. For whatever reason the heat on the plane must have been turned to FULL BLAST, because even at 30,000 feet, it was SWEALTERING. Everyone was drench in sweat. Then, they were SO STINGY with the amount of drink they would give you. If you asked for water, it was in a tiny, paper cup (think bathroom cup) and they only filled it 3/4s of the way as if the cost came right out of the pockets of the air stewards. Everything was a money grab, you could tell! You had to pay for the WiFi, which was garbage slow, and the onboard entertainment was limited and stale. If I EVER fly TAP again, it will not be Economy class. What a disaster!

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

The crew was excellent. What I did not enjoy was the food. I have taken many international flights and this was on the low end. Otherwise the trip was fine.

Seats were the most uncomfortable seats i ever experienced on a flight to Europe from Boston. It was a waist of money in buying premium seats for top dollars. I want my money back for what i paid extra for my seats. Awful conditions!

The flight crew were absolute rock stars. When they came to the gate they looked like royalty, so chic. They also were extremely kind. Food was good and I loved the lack of plastic waste. The flight was lovely and smooth.

We were unable to check in due to technical problems on TAP’s end. The flight was delayed forty minutes with no reason given. We received timely notice of the flight delay. We were also notified of a gate change. The new gate was at a different terminal. When we got to the new terminal, we learned that we had to go back to the old terminal first to check in. This information should have been included along with the gate change notification. Also unexplained, the steward skipped us when offering breakfast.

Late. Lack of updates. Rude hostesses. Terrible food. Lack of headphones.

Flight was delayed but crew gave little to no communication, then “began boarding” but really just had everyone stand up and wait for an hour without any news or updates, as if we were going to start boarding at any second. Total chaos. Seemed like this was their first time boarding a plane. When we arrived at our destination, we waited for over an hour for the baggage claim belt to even turn on. Probably waited at baggage claim for our luggage for close to two hours. Everyone was very confused and of course we all worried that the luggage was lost. Again, zero communication and everyone we asked just said “I don’t know.” So we were left wondering whether to wait, or file a missing baggage claim, or check the other baggage claim belts (which we did every fifteen-twenty minutes because we were just confused). Lack of communication throughout the experience was a huge issue.

Boarding was delayed and very confusing at Ponta Delgada airport. We were moved from one gate to another, and it was super crowded with passengers. No food is provided on flights unless you want to pay for a sandwich and chips. There is no entertainment provided. On our incoming flight to the Azores, my luggage was lost and delayed until the next day. Also, I had paid online for an aisle seat upgrade and did not receive that seat. Trying to communicate with SATA/Azores Airline is very poor on their website and by phone.

The space between seats is so minimal that there was no way to get comfortable. I will not fly this airline again.

In a 6 hr flight after paying over $700 dllrs of ticket and we still needed to pay for our own food and given ONLY a small glass of water!!! Will not be flying internationally anytime soon with them They are good for very short flights

No food was served on the flight. Boarding desk open two hours before departure. But they recommande to be there three hours before departure !! So we where a group waiting 1 hour in Line for nothing …

My flight from Toronto to PDL was one of the worst experiences of my travel history. I paid for an upgrade and did not receive it, and was also charged an exorbitant amount for a 25-inch bag, and when I tried to explain the situation, I was only told the flight was already over capacity. & I had to accept what I could get!, I am a frequent traveler and will not be flying your airline again!. The only thing positive in this entire trip wete the flight attendants, but other than that, everything else was very disappointing!

Everything was perfect, clean and very nice staff. But the seat was uncomfortable compared to other companies and the food wasnt good

Flight wasn’t full so got to stretch out and sleep.

Boarding was delayed. Then when we queued, it took us to another long line to stand in. Flight had 0 entertainment. Not even a magazine. But they had a free meal and it was good!

You cannot add an additional luggage via the check in. It seems to be an issue with Azore Airline.

This was a long flight - 6 hours - and nothing is truly comfortable for that long... but the flight crew was friendly and attentive. The airport in the Azores is small but we weren't there long enough to explore any amenities.
