Insights shared by verified travelers who flew the route from Dulles Intl to Europe 
NandiniFlew with Lufthansa-Aug 2026
Worth paying for the extra legroom in economy. The regular economy seating in UA is too cramped for a long haul flight
Verified travelerFlew with United Airlines-Jul 2026
Brussels makes foreigners take a lane different from locals. the local lane is very fast. The foreigner line can take hours. Mentally prepare and plan accordingly.
KarenFlew with Lufthansa-Jul 2026
I wish I'd know how big the airport was so I couldn't have booked assistance since I've got asthma. It was not good rushing through in the heat trying to get to the gate in an unformilliar airport.
Verified travelerFlew with Air Canada-May 2026
IAD tsa pre lines are short so don’t get there 4 hrs early! At Munich you do not need to go through passport control if your onward flight doesn’t land on the EU (eg if you’re headed to Asia or Middle East).
Verified travelerFlew with United Airlines-Apr 2026
Except for food, I definitely recommend flying Lufthansa. Jut to be better prepared, I would pack food if you take the flight from IAD to Frankfurt.
DonnaFlew with United Airlines-May 2026
Most overseas flights to Europe are tedious. I try to eat a little lighter the day before to stay comfortable. Also I like a neck pillow and eye coverings. We've flown on many different airlines and out of a few different airports. This flight with United went smooth, no delays. Food could be improved and flight attendants could smile a little more.
Verified travelerFlew with SWISS-Dec 2025
Bring sleeping pills. Tylenol PM or Benadryl. That one with your meal. Fall asleep in 30 mins. Wear a warm jacket and you will sleep most of your flight and wake up refreshed.. There are little "wings" on the seat headrest you can pull forward to keep your head upright for a good sleep. Put your phone on low power mode for the flight. too.
Verified travelerFlew with Lufthansa-Jan 2026
Sadly since I never could reschedule that flight I don’t know but maybe when possible allow more than a 2 hour layover if there is a possibility of bad weather.
Mary MargaretFlew with Aer Lingus-Jun 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 Airlines-May 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 Airlines-Feb 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 Airlines-Sep 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 Airways-Oct 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 Airlines-Jul 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 Icelandair-Aug 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 Airlines-Jun 2024
Get to beginning of boarding group early. Bring as little on board as possible due to small overhead bin space.
DouglasFlew with ITA Airways-Aug 2024
Check out the aircraft used, seat comfort, and quality of meal service, especially in business class.
LexFlew with TAP AIR PORTUGAL-Aug 2024
I had long wait at customs. Please plan accordingly.
RobertFlew with Turkish Airlines-May 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 Airlines-Mar 2024
Pay extra for a little better seating. Definitely worth it
MilyFlew with PLAY-Mar 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.

Airline reviews

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

the cabin was kept too hot. couldn't sleep as a result

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

Awful seating. Bad food. Staff only have one bottle of water and no cans.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

A little more friendliness from that crew of the day.

Staff didn't seem confident about the ingredients in my lactose intolerance meal

the seat has a problem. the back had a hole.

My flight was delayed so bad i missed u it so i just said never mind

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Worst service- attendants dont want to help and sat us in front of bathroom

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

We were delayed and they didn’t tell us why. There was no AC while we were on board waiting and it was very hot. We were in the last row and there was no window. We had a connecting international flight at JFK in a different terminal and the flight crew did not request passengers to let connecting flights off first and we almost missed our flight.

Excellent experience - from boarding through the super smooth flight The food was mediocre and the app could be better but overall great experience

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!

Poor. Our flight was delayed and they told me I would be fine to make my connection in Lisbon, I missed it. Then they told me my bag would be automatically loaded onto my new flight to rome. It wasn’t. It’s been 4 days and I still don’t have it.

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

Checked bG chstgr was extremely high. Over $120. It was s bsit and switch knowing an international passenger would have t9 check a bag.

On time, politeness, food okay but entertneiment mediocre with only old movie and the so called new we’re 2 or 3…

Everything went very well. I would like to acknowledge the politeness and professionalism of the staff—they are superb. No complaints.

No legroom, have to pay for everything including water?!? Water is more expensive than beer?

We liked the crew. They were competent, professional and friendly. The only big negative was our departure was delayed several times and the airport staff did not communicate what the problems were and what we should expect.

Was hard to sleep, but other then that everything was good.

We got to the runway and had to go back to terminal to have plane worked on, which is fine, but the 40 minute connecting flight was already gone because of this delay and had to wait 5 hours to get on a different flight and only got a meal voucher which I didn’t see the email until after I had already ordered and paid for food. I feel I should be compensated.

Hard to figure out how to put back the seat, how to get the entertainment, how to upload passport docs. Also, a warning in the airport that food was all for purchase would have been helpful.

Horrible. My dad was recently hospitalized and diagnosed with lymphoma and Icelandair refused to refund flight even though I had a letter from his physician.

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.

The flight was delayed and as a consequence we missed our connecting flight. Were stuck for another 6h in Reykyavik. Appreciated that we got a generous food voucher at least. Would have liked to see more information upon arrival including a person waiting for connecting flight travellers and informing already that we will not catch the flight and directing us to the office dealing with the matter; unfortunately that didnt happen and we hence first needed to find out whether flight had indeed left already and then locate the adequate office to help us with booking us on the next connecting flight. Also my suitcase broke and it is not clear whether it is happened on the leg with Iceland Air from DC to Reykyavik or on the leg with Lufthansa from Reykyavik to Frankfurt. Finally, understood that it is a low cost company but at least provision of earplugs for free would have been nice, instead of making them buy.

Had a screaming child next to us. Not the airline’s fault but still annoying.

Seats are way too much now with these new airplanes especially long flights like we had. I was 7 month pregnant and in a lot of discomfort due to small seats.

My biggest problem was the flight from KEF to DUB was delayed, which caused me to miss my connecting flight in DUB and we were forced into an unplanned 10-hour layover in DUB. Crew and boarding staff were all very friendly but this was a real inconvenience and especially uncomfortable for my disabled wife.

The seat size was more like a domestic than an international flight. In fact, i would compare the ammenities, quality and service to a short hall ryan air flight, which was unexpected for an international flight. The plane was extremely hot so sleeping was difficult. My biggest complaint was that they are very strict on carry on luggage only allowing it to weigh 10kg/22lb. I try to limit myself to a carryon so i don't have to mess with bagage claim, but the wieght restriction made it impossible. I have never had a carry on weight restriction (at least enforced) on an international flight. Will not be including them in future searches.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

good entertainment package but rather small seats for business class

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

We had almost a 6 hr delay, primarily due to weather, the e problem was that they communicated this delay and its length very poorly. The boarding was chaotic - even though they had hours to figure it out! The plane was an old 747 whose touch screens barely worked and there was a faulty USB port under my seat rest (something that wasn't labeled as being there) They organized my delayed luggage well. And I could get updates on the Lufthansa website. My shirt connecting flight charged for everything except water. Coffee was over 3€

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.
