Airline reviews

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Staff was rude. Didn’t give water for 2 hours. Worst service

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

We were given vouchers we couldn’t use with a 5.5 hour delay

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

The business class seats were smaller and closer together than other airlines.

Boarding- Good Seat Comfort - OK Crew - Good Food - Mediocre On Time - Very Good

Didn't like much. Wheelchair assistance was almost nonexistent. No one at TAP check in process helpful. On the plane, stewards were not friendly and disorganized. Food was terrible for 8 hr flight. We were skipped at snack time and even though we tried to get attention using overhead call system no one even looked up at us to acknowledge. Being at the back of first section and by the lavatory we only were able to request when they came to pick up everyone else's garbage and they were nonchalant...no apology or even choice. The 1/2 half bread with slice of cheese was a waste. Deplaning was horrible but I'll blame lisbon airport for that. Plane left late at made good time still arrived about 15 behind schedule and for using remote deplaning and bus to terminal took another 20 min to gate. Those with connections were highly stressed. Took us 2 hrs from landing to get to ground transportation and exit airport. And that was with wheelchair assistance.

Bad boarding, threat to force bag check mid journey, lines, late, buses, more waiting awful end to end.

Our steward Margarida who served us from Lisbon to Boston was absolutely fantastic! She deserves a raise. Conscientious and thorough as well as showing appropriate attention for every need.

An old airplane with very uncomfortable seats in the Comfort “class! Small, narrow, and hard seat. Entertainment options are inferior, old movies. Boarding started at the back of the airplane, as we entered the aircraft last instead of after business class, risking the possibility that the comfort section would not have room for carry-on in the overhead bin. The food was ok. White wine was terrible. Overall, the flight felt worse than cheap airliners, and the price was as high as premium carriers.

I will avoid TAP if I can, the ground experience was very poor with bad behaviour from the ground crew and it was only a bit better on the aircraft.

I had a business class ticket from EWR to Madrid with a layover at LIS for 11 hours. It was obvious that I needed to pick up my luggage in Lisbon for 11 hours and check it in again when boarding the second flight to Madrid. Before buying the ticket, I called TAP customer service. Customer service assured me that I could get my luggage in Lisbon. When I arrived at Newark airport, I immediately asked to check my luggage to Lisbon. However, the TAP employee refused me, saying that I should resolve this issue upon arrival in Lisbon. She checked my luggage to Madrid. I asked the TAP employee at the gate to help me when boarding the plane, I asked the flight attendants manager on board the plane to help me. All the employees refused to help me and said that I should resolve this issue in Lisbon. It took me 4 hours to resolve this issue in Lisbon. I arrived at 11am and they didn't give me my luggage until 3pm. As a result, I was so tired after a sleepless night on the plane and 4 hours on my feet at the airport and all my plans were ruined that I couldn't fly to Madrid. It was a terrible experiance,

The seats were not designed to comfortably see people in coach for more than 10 minutes

A good, comfortable flight with friendly crew and good entertainment options.

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We just made it to our connecting flight. A long, long speed walk!

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

We were moved twice on flights to the point we weren’t even on Lufthansa anymore. We had to fly united. Lost paid extra leg room twice. To top it all off we’re forced to pay $375 and $275, respectively for you luggage that was considered sports luggage. We were told it would be Lufthansa fares l, from the united desk, AND WE DIDN'T EVEN HAVE A LUFTHANSA FLIGHT! I’ll be calling once my trip is over on October 7th to all airlines and Kayak. This was ridiculous!

Everything went smoothly and the staff was very kind. I’m glad I purchased the extra leg room for my long flight; it was totally worth it. We were served 2 meals for a 9 hour flight which I was not expecting and they were very tasty. I appreciated them being vegetarian. Customs line in Munich was long; I had a choice to have a 1 hr 40 min layover or 2 hr 40 min layover; I took the longer layover which I was thankful for because my flight was delayed 30 minutes and there’s a good chance I would have missed my connecting flight. This was my very first international flight and I would fly Discover again without hesitation. Thank you for taking good care of me!
