There are currently 24 stands at LBA. I can only recall the following night stopping: 7 x EXS 733, 4 x EXS 752, 1 x KLM F70/100, 1 x BMIR EMB145, 1 x EZE J41. This makes 14 stands occupied, I'm sure Ive missed something here as it always looks packed at night when I go past. Even so I'm sure there are not 10 I've missed so there should be some space. FlyBE look like they're basing a Dash 8 for the LGW soon so that will reduce spare capacity by 1.
I find it hard to believe however, as Jet2 have most popular routes well covered and RYR have been complaining about wanting to do more ex LBA but can't as the costs are too high! Nothing new there then!
