N Everything was perfect from boarding to assistance to baggage in Tampa

I lost my plane and spend 5 hours at the airport arriving at Buffalo at 1 am taxis are very expensive at that time.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

The whole experience was excellent. As it most often is with Delta

We waited an hour on the runway to get a gate in Orlando

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

They took all carry-on luggage from Groups 6 -9 - I was group 5 and waiting in line to board - they made me check my luggage too. That then went to baggage claim and delayed departure from the airport. There was overhead room in my seating area - Delta over reacted. Also, had a gentleman next to me that took up 1/2 my seat.

Sorry I didn't realize I was writing a review for each leg. Please see my previous review - it applies to the entire flight, not just a single leg.

boarded at 5:30 pm, pushed away from gate at 6pm ... takeoff was not until ~6:45pm; disappointing

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

This was the first flight in the morning. We boarded fine. The cabin door was closed and we were ready to go. We were notified by the Captain that ATC issued and ground stop for 40 minutes. So, without even pushing back from the gate, we were already 40 minutes late. We actually were released to push-back and taxi at 30 minutes. But, some passengers had tight connections and were not going to make their connections. Some passengers asked about the delay and the effect on the connections and were told by the cabin attendant that all flights will be delayed and so they should be OK. However, that was not true. My connecting flight was on time and I arrived at IAH with 21 minutes to make my connection. I did and I'm happy about that, but the flight crew should not have given assurances to the passengers who might have missed their connections.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

It was better than excellent. The staff in Mason City were great. The young woman that pushed my wheelchair did more than could be expected of her. She came from India 17 years ago. I don't remember her name.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

The crew was generally professional. Though one of the crew members seemed to be easily annoyed, the others were fine and helpful. The green olives and almonds snack was really good. A great idea, and nice balance of tastes.

It as confusing with the connections and I almost missed my next flight because of the first delay with the first flight. United could have helped passengers go through immigration quicker rather than waiting with everyone else. The flight attendants were super friendly and lovely. The vegetarian food was awful- I did not finish. I would suggest they just do pasta next time

Flights were on time actually early service was good and crew cheerful

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

I had a terrible experience. My flight got delayed from Atlanta to Chicago on Monday April 6, 2026, and that led to me missing my next flight to Brussels. United Airlines didn’t provide me with any accommodation for shelter. I had to sleep at the airport in Chicago. The next flight I was put on didn’t leave until the evening hours of Tuesday 4/7/2026.

Checked in ok for 3 flights at the airport check-in desk, but apparently I was not checked in to my connecting flights even though I was assured that I was and had seats on all 3 flights. Aer Lingus departure was also delayed for 1.5 hours which gave no time to collect bags to go through customs.

No complimentary drinks or snacks offered on a 2 hour flight was disappointing but everything else went well

All aspects were excellent - it helped that the flight was only 2/3 full and I had no one sitting in my row. The Pre-check (US Passport Control and Customs) in Dublin made everything so easy when we arrived in Chicago.

I love the direct flights. It saves a lot of hassle and allows immigration and customs in Ireland, making arrival much easier.

Great. Has a problem with DOB. Fixed 4 us. Led to a 5 hour earlier flight to London!

One of the best flight experiences I've have had in along time. Would fly with them again.

So, the trip from Dublin to LA did not really happen because the flight took off before we could finish the transfer.

Very nice experience. Flight had good entertainment system and good food options. Customer service was very friendly and nice as well.

Like - the crew were nice Dislike - sitting on the tarmac for long periods after boarding and landing.

I was not admitted to the flight!!! i need a refund for this.

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

I would have liked vegetarian and gluten free options for evening dinner time flight. I would have like a pillow on the international overnight flight . The veg wrap and oaten desert on the international flight was good

We hoarded. Then we deplaned. Then we waited for 10 hours in the MSP airport due to a wheel misfunction. We understand safety but communication between crew and airport staff was horrible. When we did finally board, we were rushed on and because we were waiting for a “fresh” pilot and crew, we sat in a roasting plane with no A/C for an hour. My question is why was this flight not cancelled right away when they knew this would be a huge issue OR, why did AA not get a substitute plane, considering this was already a full flight? To me, this appears to be a complete breakdown in leadership and utter systems failure. The compensation for completely disrupting travel plans for hundreds, which we paid dearly for, was measly. While we appreciated the lodging for the night, $12 in meal vouchers isn’t going to sustain anyone for over 12 hours. “We apologize; our hands are tied” is no longer an acceptable explanation. We are so completely turned off by this experience and will definitely seek alternative avenues when we need to fly.

Crew was rude, almost 6 hour flight after horrific customs re entry line and near flight miss (unable to bug airport food) without food offerings.

Check in was rough because the check in crew did not know how to manage my international visa documents. Required a long process and 4 people to finally be able to proceed to security. They told us incorrect information several times before acknowledging we did indeed have everything we needed from the start.

Mechanical issue delayed us 2hrs and then once we landed sat on tarmac for 30mins because someone left a vehicle in front of the gaye

An delay of almost 3 hours while passengers were already in the plane kept us very uncomfortable. The food was also very limited. A bad experience overall.

Plane from partner PSA was filthy. Plastic needs to be thoroughly cleaned. Really disgusting to look at and wonder about cleanliness of parts less visible.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

It was a train wreck but on an airplane. First off, flight was delayed then we board only to hear two announcements, First weather delays in Orlando and second backup battery warning on emergency lights. After sitting on the plane for almost 2 hours they have us deplane due to the maintenance issue. We were told they were getting another plane. In the mean time, I notice another American- Orlando flight and ask the gate agent if I can switch. He says he cant help me and I'd have to walk to A13 from A37. Really!? I get down there and get a seat only to get an announcement my original flight was RE-boarding. The Then inflight there's no communication and I notice on flightaware were circling over the Gulf of America. I call the flight attendant and of course she has no clue and apparently 5m later the pilot finally tells us about another delay. Why does American always have these service and delay issues? They are my LAST choice in flights now!

Everything was spectacular except the boarding. It was just a mob of people while all groups were called over the public address system.

The Britts are wonderful to fly with and the crew were very hospitable. Again, I really wish they had been able to retrieve my carryon bag from baggage claim before the flight so I could be in a less worrisome state of mind, but that's not on them. I completely understand. The window seats with the dimmable windows were very cool!

There was a delay for the San Francisco-London flight, but we were all informed via text and email. The staff was very friendly and nice and the food was good. I do recommend that the airline offer something without eggs or something vegan for the vegetarian meal option. A lot of Indians are lacto-vegetarian, while some could be allergic to eggs/dairy.

food options were terrible. for a 10-hour flight, there should be 2 decent meals. Also, flight attendants should come around with drinks more than just at the meals.

Smooth flight. The seats were comfortable but the reclining mechanism didn't work very well. My wife's seat required the flight attendant to push the seat forward while she pushed the button. The leg support didn't want to return to its home under the seat. I ordered the diabetic meal which was full of carbs. It was low in sugar but carbs turn into sugar so was it really diabetic? Overall the flight was pleasant, long but pleasant.

Crew were nice, food was good. Boarding was horrendous. We were driven around the airport in a bus forced to climb a long flight of very steep stairs with no adequate handrails to board the plane . In many many years of flying to the US I have never been required to do this . There was no assistance for those needing help getting up the stairs to the plane. A fellow passenger helped me. No idea how other elderly, physically limited passengers or those with young children managed . It was a full flight with crowds trying to get up the stairs. It was an accident waiting to happen.

Horrible, the plane is just old and junky...Filthy restroom, seat was as hard as rock. The food, mystery side dish, inedible..geez..just Horrible. Never flying BA again

We paid for Business Class seats, but system did not have us and they were not available.

the service on Business class should be improved to be at par with industry leaders like Cathay Pacific and Singapore AIrlines. A lot of room for improvement.

I paid for a very expensive Business Class seat to and from Cairo Egypt from Charleston SC. There was partnership from states to London using American Airlines. That leg was amazing. The British Airlines leg was a joke. They used the standard no leg room 3 by 3 seats. A tray was put on the middle seat. The trip was 5 hours, from London to Cairo, thus my BC purchase. There was no screen proving tv/movie options, only a small device plug. The fold down tray and the bag of peanuts were typical of normal short run flying. The one toilet was located in the galley. We all got to know each other well. This was my first and last trip with British Airlines. I now understand why they would NEVER give me a seat chart so that I could make a selection.prior to departure. It honestly would not have made a difference, there were less than 50% of occupied seats. Apparently everyone got the memo but me. I have never felt so cheated as with that trip, got to so another going back to London, yeah. I will be sending a letter to customer service and asking for a refund. I will be photos comparing the two BC legs. OH, one more thing. The FC ticket holders got bulkhead and exit row seats. I know they had to be thrilled
