Go here :- http://www.fsairlines.net/
You will see the FSAirlines homepage and a button to register. Before you register take a look around particularly at the Database. Here you can look at lots of information. VA's are listed alphabetically. Click on the information button for 'Classic British Flight Services' and you will get an overview of the VA.
When you register you have to chose a country/airport where you want to start from. To help you decide, take a look at the fleet and where they are based and if there are currently aircraft available at that base. Aircraft bases can be found here :- Fleet Status
You will be using your real name to register at the site and you can use your 'normal' nickname as your user name for when you log-in to the site.
Once registered and you get a successful log-in, you can request to join the VA. Select 'Classic British Flight Services' and I will see your request as pilot 'real name' wants to join. Now, I don't know who you are from Adam, so please post below, along the lines that I have, with a bit of info about yourself. When I see a request to join the VA I will return here to see who you are. I won't accept the request until I see your details below.
