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 does KAYAK find such low prices on flights from the United States to Northern Ireland?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from the United States to Northern Ireland.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from the United States to Northern Ireland?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from the United States to Northern Ireland is likely to change within 7 days, so travelers know whether to wait or book now.

  • What is the Hacker Fare option on flights from the United States to Northern Ireland?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from the United States to Northern Ireland with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United States to Northern Ireland?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from the United States to Northern Ireland up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

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.

Flight from Fort Wayne to Atlanta was the smallest in terms of cabin space that I've ever seen. A carry on I've used for 20 years BARELY fit in overhead compartment. I'm 5'10" and felt very cramped. Not the best experience.

Flight from Fort Wayne to Atlanta was the smallest in terms of cabin space that I've ever seen. A carry on I've used for 20 years BARELY fit in overhead compartment. I'm 5'10" and felt very cramped. Not the best experience.

I am writing to express my dissatisfaction with the poor service and unprofessional staff we encountered when traveling with an infant. Our flight was delayed, and the gate staff failed to manage the boarding process appropriately. Due to incorrect, unavailable, or missing 'pink tag' stroller and car seat check-in procedures at the gate, we were forced to board last. Furthermore, the gate staff was rude and dismissive, causing significant distress to our infant. To make matters worse, one of our checked items—an infant sleeper/lounger—was returned to us broken. Given the unsafe handling of essential equipment and unprofessional treatment, I expect a prompt resolution regarding compensation for the damaged items.

We departed and landed early which was a nice surprise. The boarding process was slow.

N Everything was perfect from boarding to assistance to baggage in Tampa

Subpar. The seating on the plane is almost unbearable. We are literally touching and/or sitting on each other which is totally unacceptable and shameful. Pilots and crew was very accommodating and friendly.

The boarding was organized and informative but the plane was tight meaning that you were sitting on one another and extremely uncomfortable. It’s disappointing that can’t have common seating comfort on the plane.

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

I was told that they needed to check my bag at the gate and to pick it up at the gate in Richmond. No big deal. I know they can't control the weather, but we flew around RIC for 45 minutes to avoid the storm and were 25 minutes late leaving as well. Once we landed, we were told to go to baggage claim to pick up our luggage. I went to bathroom, paid for parking, and went to the assigned baggage claim location. United flight people came down with us as well. They got their luggage immediately. Next, South West people came down about 10 minutes later. They got their luggage next. We finally got our luggage around 30 minutes in waiting. Was not a wonderful experience. No reflection on Delta, but the ground crew was lousy at best.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

Flight delayed. Air broken. Cabin was hot enough to pass out. Delta shuttle’s becoming worse and worse.

We did not have enough time to make our connecting flight. As a result, we were put onto a different airline for our second leg. The different airline was NOT comparable to British Airlines, and our arrival was significantly delayed. The actual flight on BA was amazing.

Tv screens and movie selection v good. Friendly staff. They were really worried about max capacity and room for carryons. That is never fun but i had no problem finding space when I boarded.

My flight to London from Philadelphia was cancelled due to weather.

Disliked having to wait a little longer to disembark from the plan when we landed in London

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

The trip was smooth but the crew were very abrupt, snatching things before finished and being quite snappy when asked questions.

My wife and I love to travel, so we fly a lot. We've already logged 381,075 miles and with practically every major airline. But this flight was very disappointing. It started off well, with no delays and a new plane. But when lunchtime approached, all that good impression was ruined. Instead of white tablecloths, we were offered small, dark placemats, which, as it turned out, were perfectly adequate for the food. All the food offered—and my wife and I only took fish, and the meat—was not just bad, it was downright disgusting and not heated enough. The same applies to the appetizers. This was the first time in many years of traveling that we've been offered such disgusting food.

Lost luggage stuck no clothes and no word after 2 days leaving on cruise no stuff or clothes

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.

The flight was canceled 3 hours after original take off time

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Wish the food and overall service was better. They treat Business class passengers same as economy

WiFi wasn’t available to economy until the end of the flight.

Very good staff members with sincere passion and responsibility in their job.

Very please with the seating that the Kayak staff booked for us!

Worth every penny to upgrade to BC. Treated and felt more like First Class

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

They had us seating down for one hour just waiting on the plane

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

We waited at BOS at the gate for an hour and couldn’t get a drink or anything. Once in the air the service, food and ride was excellent.
