Virgin Express is no longer based in Brussels. It is based in Ireland.
Virgin Express bought Eurobelgian in 1996, a failed start up that
used to fly out of Brussels Zaventem. Branson moved the HQ to
Ireland where leases are cheaper.
Virgin Atlantic is based in Surrey, near Gatwick Airport. Virgin Atlantic
started flying in 1984 from Gatwick to Newark. It now serves Heathrow
with more flights than at Gatwick.
