FAQs - booking Spain flights

  • Can I fly to Spain on business when given short notice?

    Yes, you can go to Spain on short notice. Thanks to the diplomatic relationship between the U.S. and Spain, citizens do not need to apply for a visa to enter Spain. Your stay cannot exceed 90 days, and your passport must be valid for three months. You require proof of vaccination, travel insurance, and a return plane ticket.

  • Can I get a non-stop flight to Spain?

    There are no airlines that offer direct flights from Seattle to Spain. You can opt for a flight with a single layover or a cheaper flight with two layovers, one of which will be in New York at the JFK International Airport. You should not feel discouraged as the layovers are short and usually between 2 to 5h.

It is located at the tourism hub in Spain and easily connects to many nearby historic towns. From Madrid, you can easily access Aranjuez, renowned as the Royal Retreat, Ávila, also called Stones and Saints, and La Granja De San Ildefonso, the 15th-century palace built by King Enrique IV.
  • Making your way to your hotel or area of interest is easy once your flight from Seattle arrives at the destination airport. The transport infrastructure in Madrid and Barcelona is well-developed, allowing you many choices. You can opt for a rental car, a public bus, the underground railway, or airport shuttle buses.
  • Madrid Barajas International Airport may not be the biggest airport in Spain, but it still carries the title of being the most convenient. Not only will you incur less human and car traffic, but you also get access to their best facilities, including restaurants within the airport. You will find shorter lines and faster service with flights from Seattle to Spain.
  • Need to be free of your luggage for a short time while you figure out your next move? Fly to Spain on a flight to Barcelona International Airport. The airport offers luggage storage for both short- and long-term. You can leave your luggage for around $3 per hour and explore the airport and the city.
  • It can be a hassle to take a taxi to the airport.

Airline reviews

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

The cabin temperature was nice and cool. The wifi was not working.

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

First flight out and was 85 minutes delayed. Notification came out way too late

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

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

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

7 hours 15 min flight from SEA to Iceland with no inflight entertainment and no power to charge your own devices, also no meal service, not even any snacks/cookies. You have to buy food and the options are extremely limited (i.e. ham and cheese sandwich and spicy cup noodles). I didn't think Iceland air was a budget airline, maybe I was wrong, the cost of the ticket didn't feel like it though.

Very nice flight, easy connections in Keflavík, and friendly crew.

The flight was cancelled, so why are you asking me how the flight was?

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Biggest gripes were that the seats were extra narrow as the 4-in-the-middle taper down. As with most flight, too little leg room hurts my aging hips. Also changing the flight time to 3 hours earlier meant that we had a terribly long lay-over in one of the world's most boring airports

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Great! Great staff, great food, great flight :) Keep up the good work!!!

It was good. Nice entertainment selection to keep me busy for the timeframe I wasn't sleeping. Professional, courteous and attentive crew.

They lost my bags and I didn't get them for 4 days after. This also happened to about 30 other people on my flight from fra to MAA (I know bc we were all filing claims in line together from the same flight.)

Flight took off arrive Frankfurt fine ... and then the Pilot parked the plane for 20 minutes while waiting for a steps vehicle to arrive so we all could deplane. This caused us to miss our Naples flight by 6 minutes while running to the next gate.. We are aware of 3 others who also miss their flight. Lufthansa Support said "why miss your flight, your flight arrived on time?" We explained, they provided another flight many hrs later, no meal voucher because our "flight was ontime".

They help we received from the check in crew and boarding cr

Both flights were on time. Great selection of movies on board. My luggage didn't get lost, which made my trip very easy.

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

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

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

Connection at Hethrow was horrible..We couldn't get out of the plane for an hour as they were buying people to the airport and there were not enough busses. We had 2 and half hf between flights so it was very tight. After departing plane we had to go thru security again. People with less time in between connections missed their flights

There was a slight delay. Otherwise, everything else was satisfactory.

Captain sick. Unable to get replacement so delayed me 30 hours, many others delayed 54 hours. TOTALLY DESTROYED ALL MY PLANS, including lost my rental car which would now cost over 5 times what I paid so stuck with buses n trains... lost hotel reservations.... HORRIBLE!!!

The BA business class cabin is excellent,very comfortable for sleeping but the service could be improved.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Could have done with a 2nd round of drinks even if it was only to distribute bottled water

The second leg of my flight unexpectedly got canceled. I was stuck at the airport for the whole day and instead of flying out that morning I flew out in the evening. For some of my fellow passengers it was the second cancellation and their original flight was supposed to go out the day before. There was no reason given though getting rebooked was quick even though I would have preferred if I would have been on one of the earlier flights that day. Compensation was a £10 voucher for some food at the airport. I eventually arrived without further incident but but due to the cancellation, it was one of my more frustrating travels of my life.

The attendants were nice, but I was freezing the entire nine hours and so cramped. Please provide more blankets or make it known how to borrow a blanket for such a long flight. Even in already expensive economy class, people really need a bit more leg room and two more inches between seats to comfortably fly for 9 hours. Our family works very hard, but the extra expense of economy plus is just not in a lot of customer's budgets, and we still want to fly in equal peace and comfort. Please create future aircrafts that reveal reasonable care for us, the cramped- to- death customers more than the question of "how can we jam a few more human beings into this already cramped flight to impress our higher ups making a few more dollars. It's just Wrong. People need a reasonable amount of leg room and a blanket when the airline attendant said the extreme air conditioning could not be turned off. The food was tasty, but a bit more protein and less fluff would be appreciated. Thank you.

It was very good! Crew was very friendly, food was very good. I was on economy so the comfort was ok. Other than that, I would fly Condor again!

We had premium economy seats and the only difference from economy was legroom. Only one restroom for about 50 passengers was a little uncomfortable. Dinner was rather unpleasant but breakfast was good. Entertainment selection pretty good and you can use Bluetooth headphones. Flight attendants were okay.

Very cramped and uncomfortable for a large long flight! Not great service. My luggage was lost and is still lost 5 days later!!!

They lost my bag and have yet to find it, they won’t talk to me or give me any customer service at all. I’m now having to contact Alaska to help me because Condor won’t give me any updates and it’s been over 24 hours with nothing

Breakfast was terrible. Sugary yogurt, inferior pastry, poor quality fruits. No protein.

Really, nothing. I flew economy, and received a very good economy experience.

Flight attendants were polite but not attentive. They did not clean cabin throughout trip, and the airplane upon disembarking looked disastrous! Garbage everywhere ! The state of the cabin did NOT leave passenger with a ‘cared-for’ feeling. It looked a total mess. They also closed themselves off in the back of the plane and passengers felt like they needed to knock to get a glass of water. Very dissppointing.

The seats are too close to the ones in front.

Not a valued customer..just a herd of cattles that is being shuffled around. Employees just lie into your face. Last time I flew with LH companies. No customer service at all. The customer is their enemy.
