EasyJet Airline is a British airline headquartered at London Luton Airport. It carries more passengers than any other United Kingdom-based airline, operating domestic and international scheduled services on 500 routes between 118 European, North African, and West Asian airports. EasyJet's five largest bases in order of size are London-Gatwick, Milan-Malpensa, London-Luton, London-Stansted and Bristol. Newcastle airport is currently the airline's smallest base but EasyJet still offers more flights and destinations from here than all the non-base airports it serves. Initially booking was by telephone only, with all EasyJet aircraft painted with the booking telephone number. There is no incentive for travel agents to sell EasyJet bookings because there is no commission, a standard practice for the low cost carriers. Website: www.easyjet.com.
