With regards to FlyGlobespan,
they are the aviation department of a well respected Scotish travel company (Globespan), which has been around for years, and is responsible for most of the Air Transat canada flights from the UK. Air Transat operates them on behalf of Globespan. When Globespan announced the establishment of the airline a few years ago, there was little doubt in scotland it would be a success. The company has plenty experience and knows what they are doing.
The fact that the airline is backed by a travel agent seems to be the reason why most destinations are only a few flights a day. The idea was to offer a slightly customiseable package holiday, rather than just loco flights. If you book through the website it trys to persuade you to book a hotel at the same time...
When FlyGlobespan launched they only had 2 aircraft, and were trying to operate to all the spanish destinations from EDI
, another reason why they only offered a few rotations a week. Saves putting all the eggs in one basket, which seems to have worked out nicely. They are now expanding rapidly and buying their own fleet.
Air Scotland on the other hand was expected to flop when they launched, and many are still surprised they are flying today. They started at the same time as FlyGlobespan, and since then have changed the company that operates their flights 4 times! (Electra, Air Holland, Maersk and Greece Airways). They have announced little to no expansion, and the fleet now consists of a single 757, compared to the 2 they launched with....
Just to clear things up
