A question for both DG and LC0112G:
How many other jobs in all the services and support industries, from cabin cleaners to aircraft engineers, through to aircraft builders will be lost per thousand individual airline job cuts please?
Can it be calculated?
Not in those terms, a few airline jobs wouldn't result in job cuts at service providers.
That said, if a whole airline leaves an airport then the effect is obviously more pronounced.
In the case of British Airways, a company called GGS (Gatwick Ground Services) has a single contract: BA.
They provide all the ground handling and cabin cleaning services to BA and only at Gatwick. At a guess, that's 4-600 people straight out of the door. Their catering is provided by Newrest, again I believe only at Gatwick, so probably another 500-800 people or so. The laundry that cleans the blankets is up at Heathrow so probably won't be too badly affected beyond a drop in production.
BA does its own maintenance, so that will be a combination of redundancy, retirement and moving staff.
Associated services will suffer financially from the loss, for example fewer passengers means fewer customers for the shops/restaurants, but these won't automatically mean job cuts as they require staff to function.
The greatest financial loss out side of the direct airline operation will be to the airport with regards landing fees, and service provision (these charges are publically available on the Gatwick commercial website) such as parking (aircraft and staff), ID issuing, vehicle permits etc.
BA tends to operate its aircraft for 25-30 years, and they're currently mid way through upgrading their long haul fleets with B787, B777, A350.
The A380 is a slow, fat Concorde. A great idea, but a bit of a poisoned chalice. It's simply not a cost effective aircraft... You can't put 800 people in it because people demand a bit of luxury/space, so most are running around at less than two thirds of their potential. Also, they can't actually carry that much freight weight, which rules out freighter conversions.
Hence, for the last couple of years, most A380 operators have started dumping them in favour of more efficient twin engine wide body aircraft. Even Emirates cancelled the last of their orders for the A380, and they're the only airline who actually made it viable (in no small part due the fact theirs have amongst the highest passenger number configuration).
There won't be many left in service, if any by 2025.
