Passengers travelling through all four of the current operational terminals at Heathrow (1, 3, 4, 5) will be able to access complimentary WiFi provided by the airport operator from Saturday 1 June. Access to the complimentary service is limited to 45 minutes a day. However, members of the Heathrow Rewards loyalty programme (formerly known as BAA Worldpoints) will be able to access the service for 90 minutes a day (thus making registration in the scheme worth it for that reason alone).
