If it is Flightline that are based at Southend,UK. They operate mainly an ageing fleet of BAe 146 aircraft and some MD-80 series aircraft.
They were apparently ok to work for according to a friend a few years ago but they are in a somewhat precarious business and they have regular bouts of hiring and redundancies due to the lack of contracts. They have had a long term contract in Aberdeen for the Combined Energy consortium (Shell/Bp) to fly oil workers to and fro Scatsta in the Shetlands.
They love the odd witch hunt too.
Take them as you find them.
