Looking at CTV teletext earlier it looks likes as though Aurigny are operating their ATR72 LGW services from JER instead & ferrying pax to GCI by Trislander.
If BE get really pi**ed of I would not be surprised if they pull the plug on GCI & that would be a sad day for the island. Guernsey Airport could be run by chimps who would do a better job than the Civil Servants who currently "run" the operation.
