GSM are a very stable, cash-rich airline and tour operator. The rumours started here last night have been proven wrong - airline is still flying and will continue to fly for many years to come for many reasons.
A/C that GSM fly are new and use less fuel.
A/C leased out to AI, Air Callin, MoD, Oman Air, etc, all provide luctrative revenue for the company
Many Ad-Hoc charters taken up at short notice to cover the gaps left by Futura, so this will provide lucrative revenue.
GSM do not fly unprofitable routes - if they don't make a profit, they go.
Lots of other Ad-Hocs to come for W08.
Overall, this airline is strong, with a lot of assets that are debt-free. Projected to make a nice profit of £2-3m this year. The reason they got rid of the 600s is the lack of range for GSMs routes. These have been sold off at a profit to the company.
