Tips and tricks to help you find cheap flights from London to Copenhagen

Useful information about the flight from London to Copenhagen

Tranquil waterside metropolis

Copenhagen is a very attractive holiday destination that is popular with travellers worldwide throughout the year. A serene metropolis, this city is Denmark's most heavily populated, and you'll find a great selection of bars, cafes and historical landmarks to explore while here.

When to visit

Copenhagen is great to visit all year round, although if you don't like winter weather, avoid travelling between the months of December and February, as it's generally cold and dark around this time. Danes bring in the New Year with a bang and hordes of locals gather to the town centre, to enjoy revelries and fireworks. International Workers Day is held on the 1 May, and politicians hold speeches in the city, while music lovers get to enjoy the Copenhagen Jazz Festival, which commences on the 1 July and lasts for 10 days.

Things to consider before leaving

Lots of people use bikes to get around Copenhagen and roads are cycle friendly, while hire shops are easy to find. You'll pay around 20% more in Copenhagen than you would in the UK for accommodation, groceries, drinks and entertainment, so make sure you're prepared. Copenhagen is also an hour ahead of the UK.

Transportation, accommodation and local tips

It takes 15 minutes to travel by train from the airport to the main station with the Metro Line 2 or InterCity Train. As an alternative, take the 5A Bus to the city centre. Tickets cost around 32 DKK. Taxi ranks are located at terminals 1 and 3. There are lots of hotels in Copenhagen and hostels too, which is handy if you are on a budget. However, hostels are still quite expensive, in comparison to the ones in the UK. Public transportation is reliable, and buses, trains, and the metro, provide regular services 24 hours a day. Copenhagen is not that big, so you can walk around the city to most of the tourist hotspots. If using public transport, get a 7 day Flexcard, a 24 hour ticket, City Pass or a Copenhagen card. The last 2 are excellent options for tourists as they give discounts to various attractions and museums. The currency used is the Danish Krone, although most use credit cards for their large and small purchases.
