London attracts millions of visitors annually and is served by five main airports that - alongside other smaller airports in the city - make one of the busiest airport networks in the world. Each airport is strategically situated around the city to serve the different areas and surrounding regions. London to Budapest flights could leave from any of the five major airports: Heathrow, Gatwick, Stansted, Luton or London City. The largest is Heathrow with five terminals. Gatwick is the second busiest. Luton and Stansted are served mainly by no-frills airlines and London City is the smallest and primarily used by business travellers.

Each of London's five major airports operate flights from London to Budapest. Trains run to each of the airports from the city centre. For Heathrow, you can take the Heathrow Express from Paddington Station (15-20 minutes) or the Piccadilly Line from the centre (about 40 minutes). For Gatwick Airport, take either the Gatwick Express or Thameslink train services from London Victoria. Passengers heading to Luton can take the train from St Pancras to Luton Airport Parkway station (about 35 minutes) and catch a shuttle bus for the final leg of the journey (10 minutes). For Stansted take the direct train from Liverpool Street station. London City Airport is in the city centre on the DLR.

Budapest is a mesmerising blend of old-fashioned elegance and forward thinking culture. Visitors will be spellbound by the neo-Renaissance architecture of the Opera House, the romantic Danube River and the charming historic quarter. On the Pest waterfront you can visit the imposing Hungarian Parliament before crossing the iconic Chain Bridge to visit the Royal Palace, Castle Hill and the Fisherman's Bastion. No visit to Budapest could be considered complete without experiencing the neoclassical Széchenyi Thermal Bath and Swimming Pool which is one of the biggest spas in Europe, built in 1913. The city is filled with trendy and fun restaurant and bar options in which to while away an evening.
