MikeFlew with TAP AIR PORTUGAL-Sep 2026
The throne seats (rows 2 anf 4) are single seats, so no being the climber or" climbee" in these rows. The other seats in business class are 2's so the window seats have to climb over the aisle seats to use the bathroom. If the aisle person is reclined and sleeping, it might be a challenge. Therefore, my wife and I (fortunately) were in row 4. The throne seats also have extra space.

Be sure to get to the airport with plenty of time for special assistance. Three hours is recommended. There are long delays just simply waiting for the staff to wheel people around. Once you get an assistant, everything is extremely well handled. But until then, you’re wise to give plenty of time for them to take their time.
Verified travelerFlew with SWISS-Nov 2026
Spell your name exactly as it appears in your passport when booking the flight. If you have a middle name, use that in the booking too. If you don't have online-check-in leave in time to account for long lines at the check-in desks.

Get to the airport a bit early to complete the customs pre-clearance for the USA. It's nice that you can do it, but getting there is a bit of a maze.

Never plan any close connections in O'Hare. I give myself at least 3 hours if I have a connection. Nothing is convenient and if you need to change terminals, and you usually do, it takes forever. In addition, customs takes a long time. I entered the UK more easily than I got back into the country of my birth. Heathrow is not bad unless you need to go from any other terminal to Terminals 4 & 5. That is difficult bc there is no clear signage. Don't be afraid to ask for help. I have found people ready to help, especially if you are a senior.
Verified travelerFlew with American Airlines-Sep 2026
Arrive at least 2.5 hours for check-in. Check-in line was very long at 1030. Waited 45 minutes to check in. There is a pre-clearance check after security in Dublin, so that you don't have to go through customs in SFO. Apparently this saves a lot of time because the pre-clearance check is much faster than customs. Pre-clearance check just ask you what food items you are bringing home. Plane landed in Terminal 1 which is usually for certain domestic flights because no need to go through customs.
Verified travelerFlew with American Airlines-Sep 2026
Niece has very small, but compact and decent airport. Everything is clean. Plenty of food if you wish to buy, which I recommend before you get on the plane, get some food if you’re hungry because American Airlines flight don’t offer decent food anymore and nine hours of being on the plane, they offer you one terrible meal and hot pocket with water. Boarding was easy and was easy to find a gate.
Verified travelerFlew with British Airways-Oct 2026
London Heathrow airport is huge but very physically constrained due to surrounding development. The bus system at the airport can be confusing and pays to investigate before arriving. Bring multiple layers as cabin temperatures can be lower than expected. The Charlotte Airport is a breeze compared to Heathrow. Foreign travelers must expect long lines at immigration in Charlotte.
Verified travelerFlew with Aer Lingus-Oct 2026
Terminal 7 at JFK is very poorly signed, and even if you're already booked through on a connection, you will have to leave the airside to change terminals. Since customs and immigration are handled in Dublin, a word of caution that there are limited duty free and food options after you go through customs in Dublin.
Verified travelerFlew with Condor-Oct 2026
The airport is huge. The rental car location is far from the international Terminal 1, but there is a tram to connect the terminals. It’s convenient, but allow enough time to navigate this huge place. Also, leave plenty of time to get through German passport control after going through TSA.

Don't check luggage if you can help it. Do your own research on how to make connections to your next domestic flight and where to recheck bags after customs. Don't relly on the app or expect great assistance from AA if you're running behind between connections. Stay calm and be as articulate as you can in explaining any problem you have to AA reps. And don't take it as fact if they tell you your bags have been loaded on your flight.

Lisbon airport is huge with inadequate signage. If we did not have wheelchair assistance we may not have found the next gate. The plane did not connect to the terminal so people had to take a bus which was difficult for older passengers.

Not specific to this flight or Iberia specifically, but general advice for any long-haul flight: Bring headphones (ideally noise-cancelling) that have a wired connection and a 2.5mm jack if you want to use the in-flight entertainment system so you don't have to rely on the cheap, hot-garbage headsets airlines give out for free. Plus noise-cancelling headphones are a blessing if you have the misfortune of being seated near a screaming baby!

Make sure to tell your taxi driver the terminal you are flying out of from Dublin. My taxi driver only asked me what airline and apparently there are more than one terminal for Aer Lingus. Also go extra early when flying to the US because you go through customs while in Dublin and do not have to do it when you land in the US. As far as Aer Lingus they were amazing!!!
Verified travelerFlew with American Airlines-Jul 2026
Loved my flights with British airways and American Airlines. Be aware of long walking commute at Heathrow if you come from other airport. I found that a challenge. I had not asked for a wheelchair because I can walk but it's a long commute when carrying a heavy bag. Wished there were more travelators/moving walkways available at Heathrow. Otherwise very easy and very pleasant airport. Comfortable waiting areas at gates.

The Swiss are very efficient with passport control. They have devised a system which is quick and helpful. It would help tourists if they could explain their system so tourists know what to do in advance of reaching the airport. We had a very short connection. Our son’s had travelled that same way the day before and It was because of our his explanation that we could make our flight.

First if you are traveling from Europe to the US or UK be prepared with your patience to get through the passport control and know you have quite a walk ahead of you once you get through. Second: Prepare for the bus if going to US. The D terminal is like a bus station, limited seating and more of a set up to huddle groups together in order to climb on bus that will drive you out to your plain which involves rambling up stairs with your carry ons. Third, if flying Icelandic bring food and drink unless you are in Sage/Business class. All items are ala carte and you need to ask a steward for them.
MAFlew with ITA Airways-Jul 2026
If you are traveling with a pet, patience is highly recommended. The airport staff appeared to be unfamiliar with the documentation and procedures required for passengers traveling with an in-cabin animal, resulting in multiple calls to colleagues and supervisors for clarification on the necessary paperwork. While the staff was ultimately helpful, better training and clearer guidance on pet travel requirements would make the process much smoother and more efficient for passengers.
Verified travelerFlew with Aer Lingus-Jul 2026
I have only flown Aer Lingus from DUB to the states. It's a call that doesn't disappoint. Be aware that bag drop-off and check-in counters at Terminal 2 close 75 min before the flight, and you have to undergo extra security when flying to the US.
MaxeyFlew with American Airlines-Aug 2026
Compare American with Delta and United. Be prepared to allow for extra time to pass through U.S. customs in Dublin. The upside is that you walk straight into the terminal at DFW, and don't have to do customs there.

Make sure you get to the airport three hours early in Athens the security lines are a nightmare. They are pulling other airlines out of the line ahead of you. They are pulling other passport types out of the lines ahead of you. You will stand there forever, no matter what clearances you have. Avoid Chicago airport at all cost. The place is falling down. They are elevators are out of order a few elevators that they have have lines so long that you will never get through before your flight takes off. People with carts of luggage are trying to get on the elevators with the handicap. It is a total zoo and if the temperature is 95°, the Air Conditioner can only cool to 89°. No you’re going to sweat to death.
CherieFlew with British Airways-Jul 2026
Do not transit Madrid. Maybe it is fine as a aa final or starting point for non-stop flights but it is a nightmare for making connecting legs of a flight. Literally people were held up in multiple immigration lines and missed connections. 2 people had to get off our plane after boarding because other members of their party could not make it through all the transit lines in time. Why are people just transiting made to wait in a 3rd passport control line to leave Spain while only transiting??? Connection times need to take that into account.
BudFlew with Delta-Jun 2026
Boston is one of the most difficult airports to navigate when returning from overseas. A long walk thru the overseas terminal E to customs, then after waiting in the line to clear customs, you have to retrieve your checked bag and take another long walk to the domestic checked bag location. Then you have another loooong walk to the domestic terminal (A or C) for your connecting flight. A bus is provided, but they are infrequent and often too crowded to board. All in all, you need about 90 minutes between flight (minimum!)
BrianFlew with American Airlines-Aug 2026
Do not sit in the aisle seats with no seat in front of you. We sat in a 3 seat row with a two seat row in front of us. The person that sits on the aisle is basically the cart stopper, since the food carts are basically using that person’s knee to guide and stop the food cart. Also passengers going to and from the bathrooms are constantly bumping into you and stepping on your feet.

Plan enough time at Zurich. The procedure at the airport, especially boarding is very chaotic.

I still prefer BA for London-Boston but all services, especially food, have been declining over the years. Boston has some of the longest walks in Terminal E. Small carts like they have in many European airports would do a lot to help especially senior passengers.

If flying from Paris to SFO, I would recommend if you are not familiar with either terminal to do some research: CDG is very well organized for signage and helpful general customer service. SFO is not as well organized for signs, and the people who work there (at least upon the returning/customs area) don't seem as cheerful. The TSA agents at SFO were super nice to us when we departed! Their French counterparts are not as pleasant - they are really pushing hard to get you through security. So, again, familiarize yourself as much as possible with the different systems to herd you through to your plane and getting in and out of the terminals, and you will probably have a better experience. I recommend looking at online videos and terminal maps, along with transportation options.

We were going to Dublin, with a layover in London. Because our return layover was 18hrs long, we were required to attain a "UK Visa", which included downloading an app, uploading images of our paperwork, and paying an extra fee. The app was finicky and hard to please, and we had to scramble to do it in the airport lobby. If you have a long layover in London, even though you are heading to a different country, be aware and complete this before arriving at the airport, to save time and stress. It somehow slipped our awareness, but we could not check in without the special visa.

Aer Lingus agent booked us a 1-stop reservation via Air Canada to replace our original 2nd leg flight to LAX. I was surprised to discover the new trip only has the 2nd part in the Air Canada system, 1 day before the departure time. I spoke to the ticketing agent again, who really made her efforts to confirm a new reservation for our big group of travelers. I was not happy about the surprise, which can be of a very rare situation, while at the same time I do appreciate the agent's effort to help us get back home ASAP. Lesson learned: even with a printed itinerary, you still need to double check on the carrier website to be sure.

For long-haul flights, I would suggest providing complimentary earphones instead of charging for them, as well as offering basic amenities such as an eye mask. The meal service could be improved by using proper dishware rather than cardboard packaging and plastic cutlery. If chicken or meat is served, it would be more convenient if it is pre-cut, considering the limited seat space which makes it difficult to cut food comfortably. In addition, the cabin crew should routinely check the restrooms to ensure cleanliness and that toilet paper is always available.

Make sure that you verify that if you have a code share flight, that you DOUBLE/TRIPLE CHECK which counter to check in at. I booked a British Airways flight operated by American Airlines. The BA flight counter was closed until an hour prior to my departure, it was really AA that I needed to check in at. The people around the airport are helpful and speak English beautifully so just ask! Also, the security point is IMMEDIATELY before only 2 gates, so keep in mind for buying food/drink.

Boarding was easy, organized and moved quickly at Heathrow. Flying premium economy is worth it on the longer flights. More leg room and no checked bag fees to pay. You may order your meals 30 days in advance. One also gets a comfort bag at each seat that includes a blanket, small neck pillow, and toiletry kit with toothpaste, toothbrush, socks, lotion, eye mask. Very handy on those long flights! Bring a light weight jacket or sweater as night flights can be cooler than day flights. Be polite and smile as the crew try their best to keep you safe and comfortable.

Copenhagen is really laid back. Plenty of space at the gate. However, not a lot of shops. They have a self serve 7-Eleven! So, if you have the time and are hungry, eat before you go through to the gate.

I wish I'd known that there were food and shopping opportunities at the B gate area. This was a lovely, NOT busy place to spend time. I'd have gone directly there if I'd known. Definitely a nice place to wait.

The Lisbon airport traffic was such that I could not get an Uber to the airport. Take that into account or use the Metro which is cheap, easy and quick. I also found Lisbon Airport to be more difficult to progress through than JFK. I had thought JFK was difficult but once cleared through the TSA screening your in . Lisbon seemed to have more layers of difficulty.

Check your bags if traveling to the US if included / possible. It was a long walk for the flight connection and we did US customs and immigration in Dublin, not Boston, which was a first for us.

Be prepared to have a second security check when you arrive at your gate. They also don’t make boarding announcements so you have to figure it out yourself.

Do not let go of your mobility equipment. Do not move from the jet bridge until you see your stuff.

Arrive early to the airport, it takes a long time to check in and reach the boarding gates

Buy your seat ahead of time if you don’t want to be stuck in the middle or back of plane. It’s a shame that airlines have this added cost but it’s hard to avoid paying especially if you need to get off the plane quickly

Get to Rome airport a bit early. The lines for passport control can be long if you have a US passport. The signage can be confusing, but once you figure it out it is easy. Staff at Rome airport are very good and the lines were not bad there. Just security and passport control.
Verified travelerFlew with Turkish Airlines-May 2025
We got in line for passport control instead of going to the transfer section after arriving from Zagreb and wasted precious time. We wish there were obvious signs to show transfer passengers where to go. (Maybe we missed the signs?) The food was delicious and the crew were excellent.

Arrive early. There are a lot of flights and a lot of steps before getting to your gate.

Long walks to high gates so come prepared for a walk, especially if your older or infirm.

Terminal 3 at CDG is very bare bones, with no network lounges and few charging ports.
SherylFlew with ITA Airways-May 2025
I would not recommend ITA unless you are sitting in business class. All of the upgraded ITA seats lack lumbar support and are in poor condition. I would also recommend that unless you are ending your trip in Nee York or a close by location, that you not stop in New York on your way to a longer distance destination because the delay time can be very long. My delay was 4hrs, 45mins even though I only needed to fly to Washington DC Dulles from New York.
Verified travelerFlew with British Airways-May 2025
Gate assignments are made shortly before boarding and each letter dedicated terminal group is separated by a long walk or a crowded rail ride. The metro ride between the terminals and the city can be complicated if you go in with no research. We consider ourselves capable people but Londons rail system is a mess to get a grasp of.

A 6hr delay is going to put a damper on all reviews. It was almost impossible to get into the Delta club also. Zero conveyance. I could not use my status for anything. Makes me wonder why am I loyal to delta?

I fly coach so there is always the feeling everyone up front has more space than me. Everything was fine - on time which is the most important thing!

Great overall experience and use of the Delta One lounge was amazing!

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

The gate attendant was not clear w message on flight delays.

Chairs don’t recline and the ones that do recline, barely do recline. It was most uncomfortable flight i ever been on.

Good service but not on par when compared to foreign flag carriers.

Travelling with 2 others for work. Delta asked to check their carry ons due to the fullness of the plane. This was all good until the next leg of the flight. One of the 3 had their carry on checked through to the final destination but their passport on in their checked bag. Which they could not get to and he was not allowed on to the plane. Even though Delta had to retrieve his bag, because he was not allowed on. So they got his bag and he was in the terminal, but even when the flight was delayed, due to mechanical issues, he was not allowed to come onto the plane. Since the delay was nearly 2 hours, he was finally allowed back on the plane.

good in general food is just snack and beverages (same snacks all the time) could you try to change them?

Excellent hard product, excellent staffs. Lousy app and website that can’t be trusted. App says I have to change my flight due to operational issues. Message was cryptic and misinformation. Have to contact my own travel agent to make sure flight wasn’t cancelled despite Turkish Airlines app and website both denied checking in. Went to airport and had no issues checking in and boarding passes issued.Frustrating and anxiety ridden 24 hours before flight time.

Excellent!! The flight had a chef onboard and each course was served separately from a gourmet cart. Haven’t had this experience for a long time for business.

Boarding was slow -- we ended up being late to take off. It was a packed flight, and there is no effort to board in any orderly fashion. The signage went up pretty late too, so figuring out where to go added to the chaos. The food disappointed me this flight with choices that were not totally to my liking.

Everything could be better.Call center is so bad.You can't fix anything with them.

I’m leaving it really bothered me. My bag did not come in on time and I had medication in that bag that needed to be in the refrigerator and I still throw it out. Are you going to buy things because it came so late

The food and drinks were good. Other than that airplane cabin and bathrooms were dirty and airplane was HOT.

I did not like 2 3 2seating. The food quality was declining. The appetizers were good. But the main course was limited and I had to send back my lamb chop which was too dry. The meal before landing was disappointing and not appetizing.

Very good. As expected. Have used their service several times. Highly recommend

Again the lounge boarding process were the only flaws. I was sitting comfortably in the overcrowded , under-catered business lounge at IST and got a notification in my phone that boarding had started. I rushed to the gate only to stand there an additional 5 minutes before boarding actually began. I could have enjoyed additional time in the lounge. At least they clearly separated business and economy classes in the boarding area so it wasn’t a total mob scene.

waited standing in security corral for an hour with no updates

Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.

We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.

Waited on tarmac for approximately 15-25 minutes before taking off. When landing, the time it took to taxi to our gate was the also 15-25 minutes.

Waited on tarmac to take off for approximately 15-25 minutes. When landing, the taxi to our gate took a similar amount of time. This happened on both of my United flights.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

Loved the easy process to board and the experience overall was smooth

Set on the plane for two hours before pushing off the gate due to the power source issue being fixed which was known before letting people board the plane. On top of that it was very hot as AC was not working properly. Terrible experience and limited communication provided by the crew on the status of the issue. They should let people deplane while issue is addressed instead of frying them and glued to the seats.

I am United’s newest fan. The planes are clean, the staff is so friendly and snacks are more than just old pretzel crumbles. The captain came and said hello! Truly amazing experience

1 person checking us as we boarded, left gate on time, 12.30 we are told we were held for 15 mins as other flights were waiting to take off, captain due to rain … they were having a longer gap between take offs , 3pm we took off , they went land route via New Orleans in to Florida landed at 5.45pm offered coffee and a biscuit

Service was slow Flight was very loud at back of plane

The plane was delayed about 3 hours for takeoff due to mechanical/electrical issues. The actual flight after takeoff was smooth, piloting excellent, landing great. The food served before landing at CLT airport was terrible.

After flying on Icelandair to England and getting a greeting glass of champagne, free drinks and salmon I returned to the US on United for around the same price and got told immediately that I would have to eat a vegetarian meal because everything else was gone and every time I paused thinking in flight entertainment I got advertisements on the screen. On the Icelandair flight I had a great selection of documentary films and on United I was reduced to watching the Spider-Man movie. Guest which airline I look forward to flying again?

I'm a nervous, autistic adult. The staff were very friendly and answered my questions and came by at regular intervals to check everyone's comfort. They even resolved a fight between two couples in front of me!

Such a comfortable flight! Food was yummy and staff was very friendly! Will absolutely fly Lufthansa again.

There was a stewardess walking up and down and keep spraying room refreshner on people heads and faces. I had to bread this and smell like a room freshener afterwards not to mention was keep falling on my face. It was terrible.

The flight from FRA to SFO was uncomfortable. The crew allowed people to change seats after boarding finished, but then made some people move back to their seats but not others, which resulted in my wife and I having to sit in two middle seats for an 11 hour flight. The entertainment system was not working well throughout the flight, and stopped working completely around hour 8.

Inflight food quality is definitely declining. Only one hot food was served and rest of were boxed meals. That’s not how was done before. Better to fly Asia or Qatar carriers for better service.

Economy plus on a long flight with Lufthansa was wonderful. Service starts with a pillow, blanket, slippers and care package waiting on your seat. An it just gets better from there.

The Linate Milano flight was delayed. Landed at Frankfort at 12:10. Then took the bus on the tarmac and the bus ride was about 20 minutes due to the airport traffic. Got off bus went to passport control, used the kiosk scanned passport, took photo and finger prints and proceeded to wait in line. I asked the attendant that I had a connecting flight at 12:50 his respond was you have to ask the other travelers in line to let you go ahead. There should be a better system. Passed passport control and the gate was at Z69 to the other end of airport. Ran there out breath, I was last person to board due to a mechanical:electrical issue plane took off 2 hours later. Lufthansa need to a better job with international connecting flight. A 1-15 minutes is not enough considering the doors typically close 15 minutes prior to take off. So the window is reduced to 1 hour with all you have to go through with a slight delay it is not enough time. The crew on the flight was excellent and received exceptional customer service.

Loved the towel at the end. Service was frequent and perfect.

The boarding area was crowded with inadequate seating. Flight delayed which made it uncomfortable.

Terrible we had to wait out in the cold for transfer bus to take us to the plane. Once we finally got on the plane seat had no cushioning not comfortable at all. Food was overcooked and dried out. I was skipped over when they served drinks I had to call them back to give me a drink with my food. Overall terrible experience this time. I have used BA before and never experienced service like this before. If this keeps up I will look for other options

My experience on this flight was good. The seat I had had a lot of leg room, but it was so close to the aisle that the flight attendants kept bumping into my visual monitor connected to my seat to watch tv.

It was fine, but it cost me twice as much to return to Boston as it took me to get to Heathrow from Boston two weeks prior. I flew on Jet Blue over and it was half the cost of British Air.

Staff and comfort were great but first choice meal was unavailable even in row 21.

I have flown on British Airways, many many times and will continue to do so! Always the greatest service and staff!

canceled flight. needed to fight to get same fare class. now they have canceled return.

Cabin crew was very good. No wifi and no doors to the suites

Would not let me board with my fragile guitar so had to check it in. Who knows what the icicles did to it. Not happy. Had to run to catch my connection in Heathrow. After a bus and a train? Was asked by a guy in the middle seat to change my window seat with his girlfriend's middle seat further up in the plane and I was insulted. What nerve! The food was unhealthy and the seat was cramped. Could not wait to exit.

need more US friendly food options. Directions on getting to the next gate were terrible - resulted in long walks to the terminal and then finding I couldn;t enter there and had long walk back, then train to security then train back to where I started in the first place
