Personally I think that one of the problems with Skybus operations to ISC is the lack of connectivity and protection for customers.
Where can you book MAN-ISC for example ?
Perhaps a codeshare with BE could be a good idea here and route passengers via NQY & EXT.
Having to book two tickets with little or no protection in the event of irrops is not ideal to most travelers, especially considering the fog issues known to cause issues to Skybus.
