Insights shared by verified travelers who flew to Europe 
AndieFlew with JetBlueBNA-ISTJul 2025
Don’t take a taxi to the city. There is a local bus that has a route with several stops all the way to Taxsim for &6 per person. It’s downstairs where the charter buses line up and you pay at the bus!
GeraldFlew with Virgin AtlanticSFO-LHRJun 2025
Virgin Atlantic uses terminal 3. Much faster clearing customs than terminal 5
Verified travelerFlew with LufthansaJFK-MUCJun 2025
Wearing comfortable clothing is really important. ( it’s a long flight)
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.
Verified travelerFlew with Aer LingusBOS-DUBJul 2025
Whatever airline you choose, spring for a class with more leg and overall body room than economy (or whatever the cheapest class is called).
himanshuFlew with Aer LingusEWR-DUBJun 2025
Eat and drink before boarding. Snacks. Hand gel and surface wipes . Don't expect a window if in a window row.

Make sure you do not need the transit visa.

Try and bring your own water on board
PatrickFlew with DeltaBOS-AMSJun 2025
Be prepared for a very confusing time in Schipol airport where directional signage is not helpful. In one visit our group had to be escorted to the particular carrier’s desk as we were told we’d not be able to find it ourselves.
Verified travelerFlew with British AirwaysEWR-LHRJun 2025
Pay for your bags at time of arrival and not through a third party site, they will rip you off!
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.
Verified travelerFlew with British AirwaysIAH-LHRMay 2025
Heathrow has good signage. There are lots of people going to the same terminal waiting for the train. Be patient and when you have connecting flights choose a 2-hour layover.
LisaFlew with British AirwaysPHL-LHRMay 2025
Make sure you have enough time in London if you have a transfer flight. I would recommend at least 2 hours.
Verified travelerFlew with British AirwaysEWR-LHRApr 2025
Be ready for checking luggage and going through security. We did and sailed right through.
Verified travelerFlew with IberiaORD-LHRMay 2025
Get to the airport early so you’re relaxed. Con yourself into believing it’s bedtime and try to sleep so that you can keep going all day when you get there. If you can afford more comfy seats it might be worth it - though I always have the cheap ones so I can’t say for sure. Try very hard not to. sit in the middle. I’m small and the guy next to me played games all night and didn’t care that he continually ( with every move) jabbed me with his arm. This was my first flight with Cheap Flights and it was far less convenient than other times I’ve flown overseas.
RadicalFlew with American AirlinesPHL-LHRMay 2025
Don’t put everything in your gate check bags. Make sure you have clothes in your carry on

Make sure you have plenty of time between flights if you are delayed.

Take a pillow you can sleep on and rest.
JamesFlew with American AirlinesIAH-LHRApr 2025
Try to avoid Heathrow! Not the most convenient to get into London unless you have a driver. Also, Heathrow needs better signs on where to go to exit and better wifi for foreign travelers.
Verified travelerFlew with LufthansaDEN-MUCDec 2024
Lufthansa was an excellent experience, everything well organized and on time. If you desire healthy snacks, that I would advise bringing them with you. This is pretty much what happens everywhere.
Verified travelerFlew with LufthansaIAH-AMSDec 2024
Bring some thing with you for seat padding. And check in and get seat assignments as soon as you are allowed to pick them

Don’t forget you can pinch and slide the headrest up and down for maximum sleeping comfort.
TressaFlew with LufthansaDEN-LHRDec 2024
Make your layover longer because you will need it for all the walking at Heathrow

It’s a long flight. Find the most comfortable travel pillow it helps a lot.
Jose AntonioFlew with TAP AIR PORTUGALMIA-LISDec 2024
If you have connections make sure they are at least tree hours from your landing time
DinaFlew with United AirlinesORD-LHRJan 2025
Anticipate delays, prepare for long walks through Heathrow to baggage claim or for connections.
Verified travelerFlew with Austrian AirlinesEWR-VIEJan 2025
For families, don’t expect your strollers to arrive at the airplane’s door.
Verified travelerFlew with SWISSORD-ZRHSep 2024
Bring a neck pillow and a heavy sweater bc it does get cold. I used the blanket for my legs. Also: get a seat in the aisle.

Bring snacks! Might also want to bring a seat cushion. Spend lots of time thinking about how happy you are that you got a cheap ticket!
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 .
Jean-LouisFlew with LufthansaATL-FRAOct 2024
If flying business class look for seats towards the front of aircraft. Sleeper seats are comfortable but nothing like Deltas current Business Class configuration.

Make sure to leave plenty of room for layovers
BradFlew with IberiaBOS-MADOct 2024
Make sure to book your own seats and don’t leave it up to someone else. We were supposed to have window and aisle seats and did not. We had to sit in the middle of the plane which is cramped and difficult to move let alone eat.
TapanFlew with British AirwaysSFO-LHROct 2024
Great baggage policy in BA.. The worst part was experience at London Heathrow airport. Security was slow, too many people. Almost lost connecting flight even with 2 hours layover.
RuthFlew with United AirlinesORD-AMSOct 2024
Facial recognition seemed to slow boarding down, not speed it up. Why don’t airlines board from the back to the front? That would certainly speed things up!
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.
RachelFlew with American AirlinesJFK-LHRNov 2024
London Heathrow is absolutely disorganized. You need 2 hours between flights at a minimum.
RolandoFlew with British AirwaysJFK-ATHJun 2024
Purchase one of the memory foam pillows you will not regret it. They provide one for you but it’s fairly small. Try to keep your personal item small so that you have as much room as possible for your legs.
OzzyFlew with French BeeLAX-ORYAug 2024
Pack light, a carry on is perfect for a week in Paris and you’ll save time by not waiting for your baggage. Also Orly airport is not as busy and has convenient transportation to all places
Verified travelerFlew with LufthansaIAH-FRAAug 2024
The 747-8 had a galley where you could order food and drinks outside the normal schedule. Very convenient if you have an aisle seat.
Verified travelerFlew with LufthansaDEN-MUCAug 2024
Be early rather than on time for unexpected delays. The amount of travelers during the summer can be intense

If you have the space, pack your own food, just make sure it’s not smelly.
Verified travelerFlew with IberiaJFK-MADJul 2024
Spend the money to get Global Entry that’s it
keithFlew with United AirlinesIAH-MUCJul 2024
Regardless of Munich as a final destination or connection, you need to go through passport control, which was not organanized well. I had a connecting flight 90 min after landing, and I barely made it. The line for Passport control had about 500 people in front of me. Be prepared for this when booking if you have a connecting flight.
ChadFlew with American AirlinesDFW-FCOJul 2024
Absolutely get in the earliest boarding position possible if you want to get your carryon luggage on board. If you are over 6’0’ invest in a a quality medical plan for chiropractic care or consider setting appointments with your health care professionals prior to the trip to ensure you can get help when returning.
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
HashemFlew with United AirlinesEWR-LHRJul 2024
I don’t think any airline has the best boarding. Maybe American Airlines has the most comfortable and up-to-date airplanes. Always go super early to any airport leave an apple AirTag in your bag always ask Agent if your chair and or seat will be properly working
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.
Verified travelerFlew with ITA AirwaysSFO-FCOJul 2024
Pack light as they only allow one carry-on weighing 17 lbs or less. Economy seats are typical in that they are smaller with not much leg room and only tilt back to 120 degrees
Verified travelerFlew with IberiaCLT-MUCAug 2024
American boards the front of the airplane first so there wasn't very much room in the overhead bins by the time the people in the back of the airline boarded.

Make sure your passport isn’t expiring within 6 months of your flight. Check in online. And get an e visa

Also bring your own headphones with the appropriate jack that can plug in, they may not have one for passengers for free. Food is good but they may run out of what you want.
HelenFlew with LufthansaLAX-FRADec 2023
Board the flight with everyone since they don’t seem to check and the boarding scanning is no longer a scan of your documents. You walk through the gate one person at a time, even the kiddos. Luggage bins were so full. Check it in and don’t forget air tags. That provided great comfort to know your luggage’s proximity.
Verified travelerFlew with British AirwaysBOS-LHRJan 2024
Leave plenty of time if connecting in London as most connecting flights are in a different terminal which requires a bus or tram ride. Also if you’re not at the gate 30 minutes ahead they will not let you on the plane. Apparently this is a Heathrow not airline rule.
Verified travelerFlew with Turkish AirlinesIAH-ISTFeb 2024
Don’t pay extra for assigned seats, they will put you wherever they can, Eat less than 1/2 the food they bring. Drink more water. If you plan to use your noise canceling headphones, the still use the older 2 pron outlets, bring your old adapter!

I would suggest calling the airline to make sure that their TV screens work on the back of the seats, and if they don’t work that the entertainment option would work on your cell phones.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

We had to deboard 2 times due to maintenance issues. They changed the plane, and then we got deviated to LAX due to maibtenance issues on the other plane, had to sleep at LAX and los a full day.

Everything was good, except the seats in economy were so close together, you could barely get out when the seat in front of your was reclined. If the airlines keep jamming in more and more seats, it will become intolerable. I will look for another airline that considers customer comfort and does not keep adding more rows of seats for more profit.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

IAD with the archaic people movers is just a place to be avoided.

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

Tastless food and too obvious lack of enthusiasm for service in the economy vesus business class

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Don’t know they cancelled the flight day before I was to leave. They sent a email at 9:00 pm at night saying they cancelled. That is the smooth way to say we don’t want your business! I think they didn’t have enough people booking so they cancelled the flight! It’s all about the money anymore there is no honesty in business.

Having to reschedule flights a day later, they loaded by luggage on the wrong plane from Little rock now I have to HOPE they deliver it to where im staying like they said would. International flight crew was very disgruntled and not very friendly.

We will be writing a long, detailed letter to corporate about our awful experience with American airlines.

It took way too long to diagnose and solve the problem of a broken crew member cabin seat. Though compensation for the volunteer who left the flight was very kind.

The entertainment package was vast and the selections were very current. Keep updating it was great.

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

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.

The plane was delayed by two hours in Chicago which led to us missing the next flight. Lufthansa rebooked the flight and booked us a hotel for the night in Frankfurt. The level of customer service and getting us taken care of was superb. The flight crew and the service on the ground was superb.

It was a short flight, everything was good with it.

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Stop charging for alcohol overseas flights and start taking cash again not everyone wants to pay with card if the person is bigger give him seat on the outside seats not the middle in between the people is common sense and mainly if you fly for Lufthansa provides the sam service and experience...

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!

Booked Economy but it translated to economy light for Lufthansa so now we are stuck paying an extra $75 per person both ways for our checked bags. If I had known that, I would have never booked these tickets because it came out to be more than other options. The booking in the kayak side clearly says Economy and has a link to the inormation for Lufthansa which states Economy included a checked bag. Super annoyed about that.

The flight from Dulles to Munich was just okay. The seats were comfortable and extra foot room was noticeable in comfort plus. Disappointed in the booking in so much I requested an aisle seat and then was assigned a middle seat. The food was inedible. Movie choices were moderate. I usually fly Delta, but this WA flight was cheaper. Next time, I'll happily pay the extra to fly Delta.

The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

Three major things that led to my low rating, 1. Internet wasn't available for the whole time, and 2. TV became available way into flight, after numerous system reboots, and 3. Food is not good at all.

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

Didn’t fly with them as someone had cancelled my flight

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

Online check-in 24 hours in advance something seems not so easy to check in to pick seats and to print a boarding pass

I like the crew, very welcoming. Food can be better. The seat arms don’t go up so. I could use the empty seat next to mine to relax better. 3hrs delay 😠

Boarding was efficient and quick, crew was very attentive, seats were comfortable.

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours
