SYD to LHR Flights

Sydney and London Airports

Leave the land of Oz and for some tea and biscuits in London, England. Despite the hefty distance, cheap flights from Sydney to London do exist, and you can find them here on Expedia.com.au today. Head to one of the world’s longest running international airports, Sydney Airport (SYD), and see history in action before heading to a city with two millennia under its belt. Park at the international terminal (T1) in the P7 car park, then head inside to get a final view of Oz from the Terminal 1 Observation Deck. If you managed to bribe your mate to drive you to the airport, head to the departures level at the international terminal instead.
