Flights from Washington, D.C. to Europe: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Washington, D.C. to Europe 
Mary MargaretFlew with Aer LingusIAD-DUBJun 2025
Some people may be required to check their carryon bags, depending on flight, plane size, check-in crew, etc. Also, taller people should purchase aisle seats.
DorothyFlew with United AirlinesIAD-CDGMay 2025
Fly late at night so you arrive later in the morning and can have a better chance of encountering less traffic if you take a taxi from CDG to Paris. Another alternative is the RER-B which is located in Terminal 2. There are easy ways to get to Term 2 from Term 1 or 3. The ticket machines are located in the train station.
DeeFlew with United AirlinesIAD-LHRFeb 2025
For me the best route to LHR is the late night departure on UAL. The flight is often roughly 6.5 hours so I skip dinner, use an eye mask and earplugs and try to sleep.
Verified travelerFlew with Turkish AirlinesIAD-ISTSep 2024
Istanbul airport is huge with lots of duty free and shopping options. Limited food choice. And if you are on budget, pack your food in advance as everything is si darn expensive. They primarily take Euro .
EllenFlew with British AirwaysIAD-LHROct 2024
Do not check your bag if at all possible, especially if you have a connecting flight. Your bag will not make it.
Verified travelerFlew with Turkish AirlinesIAD-ISTJul 2024
Wear compression socks. If you are really tall get the seat with extra legroom Istanbul airport is hugeeeeee so be prepared and verify that you have enough time between flights if you are connecting Things are more expensive and they accept US$ but obviously charge at the euro rate
Lei-SeaFlew with IcelandairIAD-KEFAug 2024
KEF is not like American airport, not a lot of seating and gate is announced when boarding starts so be prepared to move quickly. Food is good in airport and lots of seating around the food areas.
CraigFlew with United AirlinesIAD-LHRJun 2024
Get to beginning of boarding group early. Bring as little on board as possible due to small overhead bin space.
DouglasFlew with ITA AirwaysIAD-FCOAug 2024
Check out the aircraft used, seat comfort, and quality of meal service, especially in business class.
LexFlew with TAP AIR PORTUGALIAD-LISAug 2024
I had long wait at customs. Please plan accordingly.
RobertFlew with Turkish AirlinesIAD-ISTMay 2024
Learn about the stopover in Istanbul program before you book so that you may be able to take advantage without having to pay for change fees or fare changes.
Verified travelerFlew with United AirlinesIAD-FRAMar 2024
Pay extra for a little better seating. Definitely worth it
MilyFlew with PLAYIAD-KEFMar 2024
Come at least two hours earlier than your boarding time. These “discount” Icelandic airlines are barebones with instructions. Eat outside the airport beforehand. The food sold on Play is very overpriced.

No vegetarian option was provided for the regular meal or the pre-landing snack.

The Scandinavian flight was excellent, however the second flight was partnered with TAP Portugal which was not so good. crowded gate area with no chairs, delayed flight, bad boarding process, no entertainment system onboard, and the baggage didn’t get to the carousel until well over an hour which caused our taxi that was waiting to leave. Love SAS, hate TAP.

Great logistics and timeliness as we arrived quite early. Flight smooth and fast. Excellent entertainment. Plane itself was a bit tired and the crew mostly indifferent. Baggage took forever but that’s on CPH. Would use SAS again for sure.

Will not recommend SAS for business travel. Food was so-so. Service was very good. First leg was very good. Second leg from Copenhagen to Barcelona was terrible. We paid a LOT for business class and to have seats worse than most coach seats with no entertainment and no charging available for 1/3rd of the whole trip was not acceptable. Very disappointing. I thought they were coming back in the U.S. with style, NOT YET.

I do not have a problem with the airline but both my two suitcases that were supposed to go from Hawaii to Copenhagen didn’t get on the plane in Seattle. I arrive on Monday the 21st at 10:30 in the morning. I did not get my two suitcases before Friday late afternoon that is unacceptable.

No choice of food. Needed to pay more even for a can of coke!!!

The seats were really close together and hard to get comfortable. The food was okay. The cheese was amazing! I loved the cold towels they gave us.

When my flight was changed from delays they were quick to rebook me.

I really enjoyed how clean and big the aircraft was, as well as how friendly the crew was.

Airline left me stranded in the U.S. gave me an unrequested refund of 40% of booking and canceled my trip back! When I asked why, the said “we don’t have to tell you why”. “But you can rebook”. Never again! Paid 2x and rebooked on Austrian. What a joke!

7 hours delayed due to operational issues on United’s end. Basically laziness.

Short flight but an "eager to help" crew made the journey more enjoyable!

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.

If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

They had a 4 hour delay and left my luggage in Iceland and it didn’t arrive in Portland until 11/1

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

Service was excellent. Food and drinks were very good except for a greasy lump of a donut at the end of the flight that left us both feeling internally disgusted.

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

I flew Icelandair with my partner from Prague to the US. Overall flight time was around 12 hours, with a connecting flight in Iceland. I have flown internationally for years and with multiple airlines. Every airline serves you a meal when traveling internationally. Icelandair not only did not offer an inclusive meal, but they did not even offer a snack. The only things they served over our long flight was water and coffee. Ridiculous! Never again will I fly with Icelandair.

It was good. The air plane is clean and staff were friendly.

Plane was delayed, reading the gates on their screens was horrible. They posted it a half an hour before the plane boarded. By the time I got there with my premier boarding they have filled the plane because it was over booked. Gate closed at 12:03 I was there at 11:54 plane took over around 12:20. I was told they would put me on the next flight. I had to go to TAP information desk. They didn’t give me a voucher they just said they would put me on the next flight. At the desk I was told I had to punches a ticket. The woman said buy it online because it’s cheaper. It in fact was not cheaper. But I had gotten out of the long line that formed so I paid 200$ for a new ticket. At a later flight, not the next flight. I had checked my bag and was told it would be on my new flight. I was then bumped to an earlier flight and was told my bag would also be on my flight. After landing in Madrid loosing a day in my hotel i landed without my bag. They didn’t load it on any flight that day. It arrived in madrid the next day. Essentially ruining the first two days of my vacation. I’m now seeking compensation.

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

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.

The person at the checkin was very helpful. We couldn’t check in through the keyosk, but the agent was very helpful.

Check in was excellent thanks to the team at the check in counter. I was disappointed to see that one has to pay for coffee on the flight. This is the first time I have seen that after 60 years of flying.

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 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

Flight was fine. Second meal ( fish sandwich on hard roll) was awful. My suitcase didn’t make the flight. It had been located, but won’t be delivered until tomorrow. Five days after flight

Airlines have to stop assuming passengers bring entertainment. Provide it like you used to in business class and above!! N

I don't know about the others but the flight attendant that took care of us had the absolute wrong approach "how do we dare asking for water or anything else for that matter"

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Not my definition of first class. No leg room and barely any recline. The food was good. The crew was great. The comfort for the price I paid for London to Cairo was highway robbery. The Wi-Fi didn't work for me either.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

The flat beds. Other than that, the place was not clean.

Moved me away from my family and refused to fix it.

I have always been pleased with their service. Would not change a thing

Seating and food was the worst we have experienced in 35 years of traveling for both personal and busines .
