    A historic city

    Boston has a historical aura matched by few American cities. It is among the oldest cities in the country, having been founded by English Puritans in 1630. Events leading up to the American Revolution took place here in the 18th century, among them the rebellious disposal of a British tea shipment to the bottom of Boston Harbor.

    Notwithstanding its revolutionary past, today’s Boston is a peaceful place. For those who like to explore by foot, there are plenty of idyllic paths to choose from. Saunter through the well-kept grounds of Boston common, the oldest city park in the United States, and through narrow lamp-lit streets in the downtown area, populated with houses betraying the English origin of the city’s founders. Visitors who follow the designated Freedom Trail in downtown will pass some of the buildings and locations most relevant to the city’s history. Boston has since the 17th century been a seat of education and learning, as attested to by its wealth of bookstores and museums and by the presence of Harvard University.

    Cuisine and competition

    There are plenty of options when it comes to dining. Seafood features prominently on the traditional Bostonian menu. Have a taste of New England Clam Chowder at the Union Oyster House, the oldest restaurant in the United States. Or make your way to Boston’s Chinatown, where you will find a wide variety of Asian cuisine. In Boston, sport-enthusiasts are well-placed to experience the USA’s major competitive games. Visit the home of the renowned Boston Red Sox at Fenway Park. Or witness the Boston Celtics play the quintessential New England sport, basketball, at the TD Garden.

    Check out Icelandair’s flights from London to Boston and experience the City on a Hill first-hand.

    Add a stopover in Iceland to your journey

    If flying from London to Boston with Icelandair, why not stopover in Iceland? You could simply change planes and be in and out of the airport in under an hour, but you could also do a stopover on our island for anywhere from 1 to 7 days, at no additional airfare. You will have the opportunity to explore Iceland's natural wonders and enjoy the culture and charming boutiques of Reykjavik.
