Tips and tricks to help you find cheap flights from Dublin to London Heathrow

Useful information about the flight from Dublin to London Heathrow

Flights from Dublin to London Heathrow

Airlines serving the route between Dublin (DUB) and Heathrow (LHR) include Aer Lingus and British Airways, both of which operate non-stop flights between the two capital cities. The duration of a non-stop flight is approximately 1 hour 15 minutes. There are, of course, also several airlines that operate services with a stop-over, including SAS and KLM for example. However, given the short distance from Dublin to Heathrow (comprising only 288 miles), this would not be the first choice for the majority of travellers. The flight time from Dublin to Heathrow is only 1 hour 10 minutes on average. Flights with a stop-over are also not normally much cheaper than their much faster and convenient non-stop counterparts. Tourists, business travellers as well as those with family in Ireland or London frequently travel between the two airports and, even though not served by many low-cost airlines, many prefer the convenience of London Heathrow as a central airport, which is easy to reach from many parts of southern England as well as London.

Onward travel from Heathrow Airport

London Heathrow is a very convenient airport to arrive at, due to its excellent public transport connections to the capital city and the south of England. After landing, the cheapest option is to use the underground (the Piccadilly line from all terminals to central London). The fastest, the Heathrow express, takes only 5 minutes to reach the centre of London.

Dublin airport transport

The capital city of the Republic of Ireland, Dublin, is well connected to the airport with numerous buses and coaches travelling between the airport terminals and central Dublin. The airport in Dublin is located around 10 km from the centre of the city and has a large catchment area, encompassing much of the Republic of Ireland and even parts of northern Ireland. There is a well developed public transport network in the area, with coaches serving major cities in the west and south.
