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.

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.
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.
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).

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.
We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.
Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
If you have more questions or if you have a bad price to report to us,
please send us an email and someone from our team will get back to you promptly.
