Well, that’s my way. When I calculate the duration of the journey to the airport and add an extra hour assuming signaling failures (very popular in the UK) or delays, cancellations (also popular), everything runs smoothly.

The bus was at the centre in unusual short time in Birmingham (the drivers are mad, by the way), the train was in time, the tube in London operated without delays and the train to Gatwick was one with only a few stops. Therefore I arrived to the airport 4 hours earlier, instead of the planned 2 hours.

Waiting again... Never mind...
