Peak Season:

One of the most fascinating historical cities in the world and a sought after holiday destination, it’s no wonder travellers book cheap flights to London year round. With famous attractions like the Tower of London, London Eye, Buckingham Palace, St Paul’s Cathedral, British Museum and Tate Modern, not to mention a staggering array of shows, theatre, pubs, clubs and restaurants, visitors are kept busy from morning ‘til night. No matter what time of year a trip is planned, flights to London are always easy to find. The tourist season peaks from June to September, and again at Christmas. July and August are the busiest months, as schools close for summer holidays and likelihood of warm weather is high. Expect parks and gardens to be crowded and to queue for attractions during summer.

Off season:

The cheapest flights to London can be found during the off season from late October to mid-December and from January to mid-March. Just don’t expect fine weather, the London winter can be dismal, but people are usually too busy visiting museums and art galleries, taking in shows and exhibitions to worry about the weather.
