There have been little or no new routes for years .
The last which comes to mind was the short lived Sunair , to Billund .
Eastern to Newquay
Where would the 4 additional nightstopping a/c park? Yes, a
much larger apron (and terminal) would be needed.
Not sure the bold is needed. I've just looked back through my photo album and have a picture of 2 Air Europa B737's, an Airtours aircraft and an Eastern Jetstream 32 all parked up by the terminal at the same time (must have been around 20 years ago). Not aware any capacity has been removed since then. There is also the Southern Apron available (needs a bus to be used for passengers flights).
