I will ridicule you again then if you think a new terminal, aprons and car parking will bring prosperity to the town because that is what the council wants to build. There should be an airport job fair starting soon where 10-20 hour contracts are for the lucky ones while zero hour contracts are reserved for the rest. Very few jobs will be traditional 40 hour contracts and those that are, are usually seasonal.
Last year saw MAEL go bust, Gulfstream will be moving soon and TUI are rumoured to be looking at moving maintenance out of Luton. Hangars that use to support high paid jobs are now being used for biz jet parking or are empty. I believe Signature gave up on maintenance a few years ago leaving just Harrods and Easyjet.
The price is too high for airport expansion and should remain within its own boundary rather than inflict misery on communities.
If you believe that Luton could grow to be the third largest airport in the UK then keep on dreaming.
