Just to explain why the crew bags are often off before the majority of passenger bags (we do notice the look on your faces as we make a quick exit)
The crew bags are loaded in what is known as hold 5 which is the loose load hold at the rear of the aircraft. All gate checked items are also loaded there along with any pushchairs. A separate truck is used for this and it normally arrives quickly.
All change when we move into T5 as the crew bags will be loaded in the same canister as the First bags. This is because the crew checkin is behind First checkin. On arrival into T5 we will pick our bags up from the same carousel as the passengers.
