Nor from Northern Ireland.
However on the Belfast thread, it was discussed about the A319 possibly being limited on the Malta route due to range. Similarly could it be that EZY A319's couldn't routinely make it from GLA / EDI to the Canaries, without restrictions? Also EZY may not have available A320's to add Canary Island routes from Scotland and Northern Ireland. Combined this may lead to issues regarding longer sectors from these airports.
BFS also has EI doing TFS and ACE, and as you have stated FR from Scotland, along with the charters and soon LS, so maybe EZY feel this would lead to excess capacity.
