FAQs - booking Northern Ireland flights

  • I’m searching for flights to Northern Ireland from San Francisco. Which airports do I choose?

    If you want the most hassle-free trip, you should choose an airport with flights operated by British Airways with a layover in London Heathrow. From London, you can catch a flight without changing airlines to Belfast City Airport. From San Francisco, your options are flying from the San Francisco International Airport (SFO), which is 13 min from the city center, or from the San Jose International Airport (SJC), which is less busy but is a 46 min drive from downtown San Francisco. Both airports have flights operated by British Airways to London Heathrow. If you prefer a calmer airport in San Francisco that’s also closer to the city, look for flights departing from Oakland International Airport (OAK), which is 24 min from downtown. Norwegian operates nonstop flights to London Gatwick (LGW), from which point you can catch a low-cost flight to Belfast International Airport on easyJet.

  • Which airport in Northern Ireland is closest to Titanic Belfast?

    Belfast City Airport is the closest to Titanic Belfast (10 min). However, if you’re on a flight to Northern Ireland on a low-cost airline, you’ll most likely land at the Belfast International Airport, which is a 25 min drive from Titanic Belfast.

  • What is the best airport in Belfast to stay close to the city center?

    Belfast City Airport is the closest airport to the city center (13 min). Keep in mind that this airport is only served by flights from elsewhere in the United Kingdom and Europe, so you’ll always have to account for a layover when flying here.

  • I’m traveling to Londonderry. What’s the best airport for a layover?

    Londonderry is served by the City of Derry Airport (LDY), which receives regular flights operated by Ryanair and Loganair from London Stansted (STN), Manchester, Edinburgh, Glasgow, and Liverpool. The airports of Manchester, Edinburgh, and Glasgow are the only ones that receive flights from the United States from various cities. If you want an airport with the most options of airlines and destinations, then choose Manchester International Airport (MAN). A hub for Thomas Cook Airlines and Virgin Atlantic, this airport receives regular flights from Philadelphia, Houston, New York, Atlanta, Las Vegas, and Orlando.

  • How long is the flight to Northern Ireland?

    An average nonstop flight from the United States to Northern Ireland takes 13h 09m, covering a distance of 3867 miles. The most popular route is Seattle - Belfast with an average flight time of 14h 40m.

Top tips for finding cheap flights to Northern Ireland

  • Enter your preferred departure airport and travel dates into the search form above to unlock the latest Northern Ireland flight deals.
  • Northern Ireland is served by three airports: two in Belfast, the capital city, and one in Londonderry, about 1h 30m from Belfast. Keep in mind that nonstop flights to Northern Ireland from the United States are usually seasonal, so you’ll have to account for at least one layover in another city in the United Kingdom or elsewhere in Europe.
  • The Belfast International Airport (BFS) is the one with the most airlines and routes to choose from, but keep in mind that most flights are operated by low-cost airlines flying in from other European cities. When searching KAYAK for a flight to Northern Ireland landing at BFS, you will need to choose flights with multiple airlines.
  • If you prefer to have a layover at an airport served mostly by major airlines, the George Best Belfast City Airport (BHD) has regular flights to Northern Ireland operated by KLM from Amsterdam Airport Schiphol (AMS) and by British Airways from London Heathrow (LHR).
  • If you prefer a trip without layovers and are flexible about which airports to use in the United States, then look for nonstop flights to Northern Ireland operated by Thomas Cook Airlines. They have seasonal flights to Belfast International Airport from Las Vegas and Orlando (MCO), in partnership with Virgin Atlantic.
  • US citizens don’t need a tourist visa to enter Northern Ireland if they’re not staying for more than three months, but keep in mind that you need a passport that is valid for at least six months after your date of arrival in the country.

I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.

I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.

Over 2 hour delay for a 50-minute flight is unacceptable, especially in normal weather. Very poor communication via app

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

They delayed our flight by 45 minutes and then re-updated the departure time back to normal schedule with no notification, email, or app update causing probably 40 people to miss the flight as they left without us.

Kayak sent over to jet blue my account being Mike Callaghan instead of Michael. I have a jet blue account with Michael that was connected

Som delays but overall we almost made it on the original time.

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

They put me on a chair in between two men, one overweight who was almost falling on top of me, and the other was even uncomfortable because I was half falling because of what the other was pushing me. I stayed with. my feet were swollen from fluid retention and from being unable to accommodate myself. it was very uncomfortable. I asked for help but they told me that the flight was full and they couldn't help me. I got off the plane almost unable to walk due to the inflammation. and then at FLL airport I asked for help because I couldn't go to my next flight, which was a connection.

The walk from baggage claim to the taxi is very difficult for older people I will never fly into JFK again. It is physically challenging

Overall fine but both ways for this trip was delayed.

At least the delays were short. Business class, even in the new planes is very crowded now with crappy tray tables

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

See my previous comments. I was probably booked in business but was moved to economy

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.

Brutal delay of 24 hours on first floight the 3 hours in Chicago . Tiny seats , screaming child behind me kicking the seat … couldn’t be worse

No water on the toilets, dirty sits. 4 hours delayed departure.

Horrible! I paid for a straight flight from Chicago to London. A week before trip it changed and now I had a connecting flight. Our flight was delayed an hour and a half because our flight crew was still flying in from CA. Forty passengers ran from one plane to the next. The next United Airlines flight was delayed two to three hours because of mechanical difficulties. They had to ready another plane which took time. I missed my scheduled excursion in London. 😢

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

The American flight was a connecting flight to an international flight. The international flight has a 2 check bag rule. Despite being informed of this, American would only check 1 bag and wanted 100 to check the second (basically a 3rd carry-on) to NYC. Subsequently tsa took a sealed container of maple syrup and a few other things that couldn't be in carry-on plus I had to lug around 3 pieces of luggage for the entire trip. The American reservation was made with the international and American actually checked the one piece the entire way to China. This is one of the reasons that I will avoid American airlines if possible in the future.

I arrived to LaGuardia Airport 50 minutes prior to my 6am flight but was told that I was too late and would have to flight standby to Dallas in order reach my final destination of Jackson, MS. Hundreds of people were in my situation but the agents chalked this up to being normal for any day. Had my been able to board my original flight I would have arrived at my destination by 10:30am. I didn’t arrive until 7:30pm which included a 30 minute wait on the tarmac. Strangely my luggage arrived at my final destination at 12:30pm of the same travel day. This was by far the worst travel experience I’ve ever had.

delayed multiple times. no resolution on anything from AA customer service. was put on hold in chat to talk to manager. was 6th in line to talk to manager for more than TWELVE HOURS - from sometime around 9AM until well after I had gone to bed that evening. no explanation, no attempt to make it right. just a five hour delay because of repeated maintenance claims

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

It was freezing in there. When I asked about it, the response is “we would have to tell them” and then she just walked away and continued to serve beverages. Everyone was cold and they didn’t care at all.

I did not enjoy continuously being lied to about the amount of time we would circle Chicago before deciding to redirect to Milwaukee. Then the amount of time we would sit on the ground in Milwaukee waiting for gas, or to take off again. Or the amount of time it would then take to get to Chicago again, or sit on the runway waiting for a gate. The whole time continuously hopefully we would make our connecting flight that kept getting delayed as well. Only to scramble and miss it. Enough with the BS. Tell me the truth. "Sorry, things are backed up and your probably not going to make your flight. You should rebook on the next flight now rather than wait." You'll never hear those words from an airline. Speaking of which. If the flight has been redirected and/or is seriously delayed, how about making the WiFi free for everyone so they get to rebooking and reserving hotel rooms while still in the air. You've inconvenienced me already and now you want me to pay $20 for Internet so I can try to make other plans. Absolutely disgusting!

not enough crew for business class and not great service as a result. underwhelmed overall

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

Crew never smiled, never helped , told me to make my own bed ( in Upper class), never offered a drink

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

For the price we paid, the service was outstanding, we took off on time, everything went very smoothly, we landed on time, and we didn't need anything extra.

On a day with 1000s of worldwide flight cancellations, I was worried about my flight. Not only did my Spirit flight leave as scheduled, but it arrived at destination earlier than expected! This made my day!

The length of delays were extremely frustrating. Stuck in airport for hours. We were to get meal vouchers but it was 3 hours until someone responded to me from their WhatsApp and they said wait for an email. Still no vouchers and it’s been 24 hours. Terrible customer service. The ppl at the gates and bag checkin were miserable and not helpful

Spirit airlines is very bad airline staff doesnt know how to treat passangers they didnt allow us in the flight we reached 45 minutes ago from flight departure but they denied nd said you are late Very disappointed i never reccomend spirit airlines

spirt air lines took advantage of two eighty year olds. we paid extra for cancelation due to health reasons they did not honer they have no spirit. I hope they treat there grand parents beter.

Our flight was delayed four hours and staff did nothing to accommodate the issue.

The flight has been cancelled we have been waiting at the gate for almost 2 hours and they didn't gave me an update for rebooking

I like spirit it make easy for you to travel no matter how your budget it you find cheaper tickets on it, what I don’t understand everything it so expensive a bottle of water cost you price of a case $4 dollars that’s not fair.

Would have been better if I would’ve made it on my flight but it was delayed twice and then canceled and now I’m stuck till Monday which was and extra 5 days I did not count on .

Awful. My flight was three hours late leaving DFW and we just arrived at LAX three hours late and stuck on the runway. I heard the Spirit workers at the desk in DFW say that we were waiting on a crew. I am extremely disappointed in Spirit.

Better than expected.on time. Friendly staff in NY however MYR not so nice.

The flight crew and flight attendants are poorly trained and demonstrate poor professionalism. They have a sloppy appearance and communicate with patrons poorly. It is embarrassing for them to be representatives of an airline and for them to be called professionals.

After 5 hours of delay, they cancelled the flight. Very disappointed

My flight to LA was cancelled. I waited at the airport for 3 hrs saying it was delayed and then all of a sudden it was cancelled. Frontier only gave me a voucher and refund but could not rebook me. Flights on other airlines were too expensive last minute. I had to drive down to LA and didn’t even take my return flight home since I had to drive. One of the worst airline experiences in my life. It’s crazy how airlines can just upend people’s plans just like that.

Flying Frontiier was extremely poor!! I paid for a7:15am flight on flight 1601 from PHL To Las Vegas and the delay was brutally, excruciatingly and disgustingly long (8 hrs). I arrived by Uber to PHL at 5:30 am and had to spend the entire 8 hr delay inside the airport. Even more atrocious was that the flight was delayed twice. On the phone with customer service for two hours and was not fully compensated. I feel taken advantage of with this airline. They offered a menial couched for another flight within 90 days to me and my husband who has never flown but this experience has made us almost 100% sure to not fly this airline and will suggest that others don’t either. We don’t want to book ever again, don’t want a menial voucher and I believe by standard and because the flight was delayed for 8 hours, I should be fully reimbursed for the entire round trip. There is no excuse why this should have ever occurred. After sharing my experience with others in Vegas and Philadelphia, I was told that Frontier airlines is notorious for long delayed flights, poor customer service and refusal to compensate people correctly. I’m very nervous to see what departing from Vegas to Philadelphia will bring.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Flight was 3 hours late leaving. Poor communication from the staff about delays. Impossible to get in touch with customer service (by design). And it actually didn't come out to be much cheaper than a non-budget airline! Not worth the headache, I'm never flying Frontier again

I’ve never flown frontier without a flight getting canceled. I understand that things go wrong with planes, but all other airlines handle cancellations so well. Frontier becomes a dumpster fire if a problem appears for them.

Checking in was easy and simple, crew was nice and efficient, but I would improve seat assignment randomness to make it easier to sit together based on when you check in. Overall would fly with them again.

Flying Frontier was a nightmare. From the booking through Kayak, checking in, departing and arriving, I will never recommend Kayak or Frontier.
