According to figures released by the Civil Aviation Authority (CAA) for flights between April and June, British Airways suffered a spectacular collapse in the performance, trounced by its rivals on every single route between Scotland and London. It is significantly worse than its competitors at every airport, on every route and in each direction.

The figures show that a business traveller from Scotland travelling to London is much more likely to arrive on time with bmi at Heathrow, easyJet at Gatwick or ScotAirways at London City. And even when BA passengers eventually reach their destination, they are less likely to arrive with their baggage - BA is bottom of the European league tables for lost luggage, according to data from the Air Transport Users Council.
