Many long haul flights depart from London Heathrow Airport and an increasing number of low cost airlines like Aer Lingus are flying from LHR. One of the most frustrating parts of travel from London is the expense of getting to the airports around the city, which is not cheap. Taxis and licensed cabs are quite pricey but are one of the only options when trying to catch a very early flight. Your best option for these tends to be hiring a car service on a flat fee basis.
