Flights from Spain to the United States: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Spain to the United States 
ValerieFlew with United Airlines-Oct 2026
Bring your own snacks, food and stay hydrated as for with me with three flights, it can take a toll on you otherwise.
Verified travelerFlew with British Airways-Aug 2026
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!
LAURELFlew with Iberia-Jun 2026
DO NOT SIT IN A SEAT IN FRONT OF AN EXIT ROW.
Verified travelerFlew with Air Europa-Feb 2026
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.
IanFlew with Iberia-Jan 2025
Be aware that checked in bags are EUR70 per bag. You can board the plane via stairs either at the front or back. I thought the experience was ok a 13 hour flight
LisaFlew with Iberia-Jun 2024
Make sure if you have a connecting flight that you have at at least 3 to 4 hours in between.
ErikFlew with Vueling-Jul 2024
Check in online if you must fly this airline. Avoid excess weight (up to $250 per bag!). Better yet - fly another carrier. Single worst flying experience of my life. And I easily fly 150,000 miles every year with all types of carriers.
CassidyFlew with Iberia-May 2024
Check to make sure the airline you are booking through is not subcontracting it out to a janky airline to cut costs.

We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

I liked one of the movies ( which I'm not a movie person" but this was so funny. I had to keep my laughter out loud to a muffle.! I felt too squished in my window seat and the man next to me was not big and bulky or heavy. I like the option of only two seats together. It made it much better for bathroom breaks.

Was on time, normal boarding. The worst flight attendents and service I ever seen,, can't believe Delta can have such service. Bathroom was dirty and no toilet paper, paper towels and used toilet paper all over the floor, when I tried to tell flight attendant she didn't even let me to finish and turn around. Very rude. Wi fi didn't work.

I went to washroom twice and once there was no toilet seat cover and the other no toilet paper at all. I don't think it was ever replenished or checked before we boarded as it was very early on in the flight.

For some reason, I couldn't choose my seat. The airline gave me a seat when I got there. Not happy about that. Otherwise, everything else was great!

The way BCN airport handled boarding was a huge improvement over our trip to Spain from JFK. Instead of gate-mosquitos edging in before their zone was called, in BCN they had clearly marked lines for Zones 1-8 and people just lined up correctly. The flight itself was uneventful. The meal (curried chicken and rice) was one of the better meals we've had on Delta. Entertainment options were plentiful, power chargers were available in Main Cabin, and seats were decent. Flight staff were very friendly and positive throughout the 8 hour flight.

Delta changed our flight a few months prior to our trip and we couldn’t get as good of seats on the new flight. Because of that we couldn’t sit together which was very disappointing. On the flight after a few hrs the bathrooms were filthy. The seats were comfortable - we were in comfort plus. The food was not good. The dinner was average but the morning snack was uneatable with horrible coffee. We have always preferred Delta comfort plus for our overseas travel and usually the food is decent, but not this trip.

third trip overseas with delta recently where the TV did not work- not acceptable for a 8 hour flight! your food really has declined crew great and I am loyal to delta

Did not live up to expectations - lounge benefits of Delta Amex Reerve card not honored for my wife.

Premium seemed like first class, nice seats, great food, competent and friendly flight attendants. Very nice flight.

The final two flights were delayed therefore I had no time between flights and had to light job with the final leg to make it. In one instance the boarding was a disaster due to agent giving me a hard time upon entry to the plane. He advised I needed to combine my items (as I stopped to get food - no time for the business lounge the entire time) and the sandwich dropped in the floor through the paper bag. On the final flight the flight attendants were inexperienced and did not cater to my row (at all)

The entire experience convinced my wife, Cathy, and me that traveling Polaris on United is the only way we’ll fly in the future. From check-in and baggage drop to the end of the 12-hour flight, the customer service was exceptional, with numerous staff members exemplifying the very best in care. On board, Andre, our primary crew chief, was sincerely friendly, a consummate professional, and, along with Freddy, one of his team members, truly among the best of the best. The captain even came through the cabin to chat with passengers—a wonderful personal touch, especially on such a long journey.

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

There were no facilities in the middle of the aircraft and premium economy was not allowed to use the business class facilities, and had to share the only two toilets at the back with economy. The upgrade to Premium was definitely not worth it

When I went to check in at the United counter in Barcelona, Spain I had 2 different menat 2 different times in United uniforms (standing around with a couple other employees) ask me if I was traveling alone. The one man asked me 3 different ways if I was traveling alone. I am, 68 yeaers old and have all my faculties. I thought it was weird and it made me feel very uncomfortable. What difference does it make if I was traveling alone or with someone? What if I was a recent widow? That would have been horrible. They never gave me a reason why they needed to know who I was traveling with. I was hesitant to question them because I needed to be on that flight.

I really enjoyed flying with United airlines amazing experience , good customer service and great food

The first flight was an hour and a half late leaving, thus missing my connection. The second flight Departure was two hours late Leaving.

The width of the chair is very small. Not comfortable at all.

No entertainment system or wifi on a 12 hour flight. They failed to include GF meals And snacks as requested on my ticket so I had very little available to eat. Crew seemed indecisive.

Love flying United have being using United for over 12 years and always delivers value.

They ran out of food and on the flight back to NY there was no wifi nor any socket to connect your plug to charge your phone. Also the crew was not friendly as they did not want to throw out my empty water bottle after she told me to hold on to it and then said no.

Boarding slow and chaotic. Food was terrible. Flight attendants were nice. Sears were comfortable.

I feel like the boarding process could be a little better. But the staff and everyone does a really great job.

Flight was good. Would be great if we had free WiFi

Flight was late, and not sure why. The business class lounge in Porto is not proprietary to TAP, and is really substandard, almost as bad as "The Lounge" in Boston. It was a D, which is better than the F experience in Bostonm where we left "The Lounge" for a better experience in the terminal. It had better food (an extremely low bar), ok beverages, and wasn't as crowded as the Boston one, but no restrooms. To use one, you had to leave and go downstairs. There's no down escalator, and the elevator might be able to crowd 4 people. Otherwise, you're carying your bags down the stairs. I hope the Lisbon club is better, but for TAP to provide this in the 2nd largest city in the home country is disappointing. They put out an announcement to proceed immediately to the gate, but there was no plane and few seats. from the lounge, 8 people with bags waited in line for the single tiny elevator. After almost an hour of standing, we finally boarded. TAP, at least on this plane, doesn't offer a welcome drink to business class passengers. Having said that, the crew was very friendly and accomodating. We landed about an hour late and then were told we were going to be on the runway for at least a half hour because no gate was available. So, bottom line, D- for pre boarding, A for flight attendents, B + for business class food, and Incomplete for post landing.

Special meal AVML was terrible Move selections were mediocre No Wi-Fi offered

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.

Flight was delayed more than 1.5 hours. Essentially no communication with passengers regarding how long the delay would last or any updates as to the delay.

Clearer signage at Lisbon Airport and more communication about delays

Flight smooth and on-time. Food a joke, crew humorless but efficient. Really a budget airline masquerading as a flagship, but it gets you there.

Over 3 hours and 25 mins delay, entertainment screen froze on me for more than half the flight

they couldn’t not serve coffee or tea as the water that was boarded was not potable. the veggie food was lousy. tasted very sweet. there was a crying kid a few rows ahead. what about the difficulty caused to other passengers because the kid was crying so much. parents should know their kids better and not travel. it was a very difficult situation. would not recommend this airline next time.

the internet connection was poor. and the change of time

Based upon our entire experience with Iberia, we will never fly the airline nor recommend the airline to anyone. The flight to LA was fine and the crew on this one flight was god, but Iberia treats its customers (us) horribly. There was not one flight on this trip that they did not treat us poorly. We were bumped, lost seats, lost luggage etc all on flights we booked over a year in advance. Not one leg with Iberia went smoothly. And now they have lost our luggage somewhere in Madrid. This is a horrible airline. A truly horrible airline. And Underpricer recommended by Kayak is horrible as well. The lesson learned is to book directly with an airline and stay away from Iberia at all costs.

Very cheap airline, not worth the price. And they almost lost my luggage at JFK during a direct flight. I can't believe I paid that much money for a horrible 'premium economy' flight. Just fly economy on the cheapest end; premium economy is no different. Very very poor.

Boarded in group three at Barcelona, which meant going from a gate outside onto a bus to ride across the airport to a plane waiting on the tarmac. When we arrived at the plane, crew behavior told us something was wrong. Bus driver would not let us off for almost twenty minutes, despite being crammed shoulder to shoulder. Eventually, we got onto the plane, but were then told that someone “forgot” to refuel the plane and the truck to do so had not arrived. We departed late enough that we missed our connecting train in NYC, which was the last train of the evening, so we had to stay awake all night in the passenger waiting area of Amtrak’s Penn Station, which was almost impossible to get to because the station was now closing, as it was after midnight. We had to haul four suitcases a few blocks on city streets in the rain to get to the one remaining open entrance to Penn Station. We ended up being up for 36 hours straight because someone couldn’t do their job. Never, ever again would I fly this airline.

All four segments of my trip on Iberia were late for various reasons. No apparent effort to stay on schedule. Never flying Iberia again.

The flight from Madrid to Boston was awful. Without prior warning, I was seated in the row in front of an exit row where my seat did not recline. The person in front of me reclined, reducing my already tiny space further. This was the WORST flight I've ever had.

Worst flight I ever experienced, what was supposed to a 7 hour flight ended being 13 hours on a plane with no ac and the worst cabin I have ever seen. Never again.

Excellent plane, 787. Very good seat and additional stuff they provide. Good food. Very good staff.

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.

Both flights were delayed over 1 hour. And I had to pay for seats, even though my reservation supposedly included free seat selection.

The United flight was excellent! The flight attendants were attentive and nice, and the food was very good! And the glasses are larger than on Lufthansa flights! I don’t want to have to ask for 15 glasses of water because their glasses are ridiculously small!

The plane was 3 hours late. What more can I say?!.. This, plus my horrendous experience of the second leg of my trip in where the plane had to be boarded (off and on) without escalators.. but not-covered outside regular steps…!! No… this is my last flight with Lufthansa!! Never again!
