The Bru-Gotheburg route is indeed an important route.
A lot of business pax travelling on this route, so it's a route with a big potential, which has always had a high load-factor at Sabena.
Some things people have to realize here.
1. Sobelair will NOT take over any ex-sabena planes because most of them were leased. Certainly no 737 because those planes were already sold, and just leased back!
2. Virgin express did take over one 737-400 from citybird. It is still flying in the green background, but with just in white Virgin-Express on it.
3. Virgin express will not hire any crews or buy any aircraft in the near future because; their daily services they conducted on behalf of Sabena are gone as well.
They are down to 3 Barcelona flights a day iso 6.
Same thing with the Rome flights as well as the London Hetrow onces ( I don't know the frequencies of those, but should look it up.)
So it is not more than normal that Virgin-Express opens new Destinantions, because otherwise, their planes would be idled as well!
