The terminal has an area of {{convert|105481|m2|abbr=on}} and is now home to the [[SkyTeam]] alliance; except [[Scandinavian Airlines]] which uses Terminal 2, and [[China Airlines]], [[Aeroméxico]], [[Delta Air Lines]], [[Middle East Airlines]], and [[Virgin Atlantic]] which use Terminal 3. This terminal is also the base for several Oneworld carriers such as [[Malaysia Airlines]], [[Qatar Airways]], and [[Royal Air Maroc]],  besides few unaffiliated carriers such as [[Etihad Airways]], [[Gulf Air]], and [[Royal Brunei Airlines]]. It has undergone a £200{{nbsp}}million upgrade to enable it to accommodate 45{{nbsp}}airlines with an upgraded forecourt to reduce traffic congestion and improve security. Most flights using Terminal 4 are those from/to East Europe, Central Asia, North Africa and the Middle East as well as a few flights from/to Europe. An extended check-in area with renovated piers and departure lounges and a new baggage system were installed, and four new stands were built to accommodate the Airbus A380; [[Qatar Airways]] operates regular A380 flights.
