Wouldn't be suprised if KEF goes, type of route that can only last a certain amount of time before its starts to decline. Likely heavily outbound and buzz of Iceland will start to calm down.
Is Lyon not just ski so winter seasonal?
If BHX is gone I wouldn't be so sure FR will step in simply because routes like LBA/EMA have been opened, LGW late fares are still very soft and the currency slide against the euro will cause FR problems in time unless it returns to more normal levels.
