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.

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.

Great. Loved that there was WiFi on flight to keep in touch and excellent service of beverages and snacks.

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

great flight. Pilot was communicative, flight attendants were excellent. Really nice experience except my tv didn’t work.

Overall, the flight was better than the flight I took to go to Florida, which had a bunch of problems. The crew is really nice and the plane was new so it had a small problem when we were on the runway, but the flight itself was great. They even made some time back up, which is always a good thing.

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

I had back trouble prior to my flight and everyone was great about helping me.

Jetblue needs to improve on Onboarding as it seems to always be behind on departing. It never leaves on time. I would recommend to have an earlier Onboarding in order to leave on time and respect your customers time as well.

40 minute delay before take off after boarding flight. Bright lights throughout night flight due Issues with light panels. In flight Entertainment nonfunctional

Flight was delayed 2.5 hours - a big deal on an overnight when you plan to sleep.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Terrible boarding , Business class seats are sub standard. As usual crew will miss your food too

Just get Economy Plus for international flights, so worth it the extra room, bigger seats…

The return trip was a customer service disaster. American Airlines needs an overhaul of how they treat their customers.

Was flying in premium eco and there were around 5-6 movies I wanted to watch and none of those could I play for some reasons. Not just me we checked w the person sitting next to me. Few of the movies were only playable :( Also that was not great that we couldn't upgrade to business however tried to, many times before the flight :(

You cancelled my flight by email then made it very difficult to get in contact with you. Then put me in a flight with a long layover in Mexico returning to the wrong airport in uk. Mind blowing my stressful. I missed see my grand dad because of you.

This was not the BA business class it used to be. Mediocre food, attendants seemed stretched thin. All the little luxuries that used to make BA business fun were missing. Flight delayed and the explanation given was they forgot to pick up crew - I hope I misheard! Transfer in LHR “sticky” - we thought we had way too much time at 3hours but it was needed. Next time will try different route.

Always getting updates by email very easy to check in on line. There was plenty of checking in staff to get you all through. It was nice that the flight attendants took time to talk to you and were interested in your holiday.

Flight from Phoenix to London was very quiet. Excellent space available for comfort, couldn't fault

For it to have left on time! Instead of two hours early with zero notice

Flight kept delayed from morning to late afternoon so I had to make other arrangements

Crew was nice, explained emergency protocol very well. Flight took off and arrived on time. Pilot explained the small delay that occurred with docking and providing updates. I would definitely fly spirit again.

Terrible… missed our flight due to ridiculously long time to go thru baggage check-in!

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

Everything was really good but the seats are not very comfortable.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

I had no legroom, although I paid for extra legroom. I could barely put my bag in front of my feet and under the seat. The Wi-Fi was horrible. In fact the flight attendant said that they had to reboot it and see if it was going to work and never did.

The guy with severe body odor sat next to me. For the whole duration of the flight it was a torture. The airline should have better policy on limiting people with bad body odor to board the flight. Passengers should not be the ones to endure bad odor for the whole duration of the flight. The airline should be e the one to ensure decent air quality for ever passenger.

Overall it was a miserable experience... I will never fly spirit for more than a 3 hour flight or overnight.

I checked a bag because it was $5 less than carry on. They managed to lose my bag on a 2.5 hr direct flight! Frontier has no airport staff at baggage claim to help. As soon as I got home around 11 pm I tried to use their online system to file the claim for lost bag - system wouldn't take the # on my baggage claim ticket - said it was not the correct number. Also said that I had not checked a bag, which wasn't true - even my online boarding pass showed that I had checked a bag. Wasted about an hour on that process with no luck. Tried again in the morning - same thing. So tried online chat with Frontier bot - waited 35-40" twice to be connected to a baggage agent and it never happened. Eventually drove to PDX after work and waited 2 hrs for the Frontier ticket agents to arrive prior to the next Frontier flight out of PDX and FINALLY got some help from one of them, to take me to lost luggage area where I was able to retrive my bag. Probably took 4-5 hrs. of my time and endless frustration to get my bag. This was my first -- and LAST -- experience flying Frontier Airlines. Check-in was also extremely difficult and time consuming. The flight itself (and staff) were fine but everything else about the experience was a total disaster! The fact that Frontier literally has NO WAY to connect to a human voice for customer service (in this case for lost luggage) is the WORST!!!!!

Frontier is a crappy airline nothing about it is honest

I didn't get to do this flight l, hard to review

Not good 😐 Over priced baggage fees Small hard seats No wifi or entertainment options 😕

Didn't like anything!! Horrible flight. Small seating area and hard seats. Butt was sore after 2 hour flight to Seattle No entertainment or free refreshments No wifi or USB charging receptacles to charge phone entoute like other airliners Luggage rates were 3 times as much as competitors. Difficult to navigate online luggue process to pre pay before flight Overall bad experience WILL NEVER RIDE OR RECOMMEND FRONTIER TO FRIENDS OR FAMILY MEMBERS!!! THIS IS A SHAME!! MOST MESERIBLE FLIGHT OF MY LIFE!! AND I THOUGHT SPIRIT WAS 👎 YOU GOT THEM BEAD HANDS DOWN!!

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.

Flight was canceled with little warning. Flight was rebooked through Ontario, California and connecting flight was delayed by over three hours. Frontier is living up to their Greyhound of the skies reputation for sure.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.
