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.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

The flight was delayed 90 minutes The Gate was wrong The Restroom on Aircraft was not clean There was a half used water bottle in my seat

Delta is always a wonderful experience. A clean plane and the crew is really friendly.

Too many people are taking up space in the overhead bins with their extra piece of luggage. Since they cannot fit their backpacks or extra luggage piece under the seat in front of them, they store it in the overheads and thus taking up room for other passengers. It wasn’t only one or two persons; more like 12 or 13 passengers.

Excellent service, I love the soft blush pink mood lighting on the 767-400ER during meal service. The overhead gasper vents on the 767-400ER were also very strong with a lot of airflow to keep me comfortable on my flight.

This was the worse experience. They delayed our flight twice and we still had to find another flight to get home sooner which was alos delayed. Also, the flight attendant named Ginny on DL9890 leaving at 4:13pm on 3/23/26 was extremely rude.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

The return flight was great. The flight out to CDG was overbooked, and we were forced to check in a small carry-on at the get immediately before the flight, before getting out the stuff we needed on the plane.

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

Pathetic check in experience at JFK. Everything is self check in. Not enough staff present to help with when the check in process or the kiosk gets stuck. Staff present not welcoming or pleasant at all. On the other hand the NY based flight crew was great. Courteous and friendly throughout the flight. Special meals leave a lot to be desired. Kids meals should be made available when kids are flying and same goes for special kids meals too.

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.
