In the days of the council running the airport baggage handling was quite a slick operation, as their staff loaded and unloaded all aircraft. But if memory serves me right the law was changed with the handling agents and airlines taking over the responsibility. You now have the situation where say Easyjet baggage handlers can’t cope but Servisair loaders have nothing to do and of course the reverse can happen.
Cleaning, parking and running the busses to the station and car parks are now subcontracted. Oh and if you don’t book in advance the cheapest parking is now £10 per day / £150 for a two week holiday.
The first floor of the new terminal will be opened up next year as airside as part of the construction work associated with the new pier and immigration hall.
