Cheap Flights from Calgary to London-Heathrow

For many Canadians, traveling equals freedom. The UK is one of the top three destinations for Canadian travel. As the capital city of England, London receives over 31 million tourists per year. Dreams of sprawling estates, majestic palaces, and prim and proper royalty often initiate the desire. While London has plenty of the old-fashioned fancy stuff, it's also culturally advanced and just plain fun. Londoners, themselves, are full of life, and the entire region has a cosmopolitan vibe that can't be ignored.

Arriving in London at Heathrow Airport (LHR)

Canadians flying from Calgary into London will most often land at Heathrow Airport (LHR), 23 km from central London. As London's busiest airport, LHR handles the needs of over 75 million passengers annually. Four active terminals guarantee efficient service. After an almost 11-hour trip, it's nice to relax with amenities such as free WIFI, prayer rooms, a hair salon, children's playrooms, and multiple lounges including two specifically for Air Canada passengers located in T2.

Considered one of UK's best sleeping airports, non-EU overnighters are sent to T3 for sleeping needs. However, the airport has several adjacent hotels, and many more are available closer to central London. If traveling into the city, car rentals are located in the Arrivals Hall. The Heathrow Express train leaves for Paddington Station every 15 minutes. Passengers can grab the Tube between T2 and T3 or in the basement between T4 and T5. And taxis are hailed outside of each terminal.

Things to Do in London

If you're limited on time but really want to take in some major tourist attractions, head to Westminster Abbey and enjoy a self-guided walk. During the short stroll, you'll get to see several of the most popular area sights including the Houses of Parliament, Big Ben, the Jewel Tower, St Margaret's church, Cenotaph, Downing Street, and Horseguards. If you grab a bus tour, you'll likely also see Buckingham Palace, Tower of London, and Trafalgar Square in a relatively short but thorough trip. Those with more available time should definitely check out Piccadilly Circus, Camden Market, and Hyde Park.

Travel Tips to London

Bigger cities tend to have more issues with mugging and petty theft, so lock up all valuables and travel in groups. A little common sense goes a long way. London weather is mild, but the winters can be rather wet. July is the warmest month with average temperatures reaching 19° C. The best time to travel really depends on your needs or vacation intentions. Always check the forecast prior to your trip, pack accordingly, opt for a tour whenever possible, and rely on Skyscanner to help you create an affordable and unforgettable excursion.
