Groundhog, when you get off the AC flight in Terminal 1 keep a sharp eye out for the “flight connections” signs and just follow them. You’ll remain airside. The EI regional flights used to all depart from remote stands in T1 also when Stobart operated them, I assume now Emerald have taken over they use the same stands.
