Arrived 3h45 minutes before flight to Madrid, after driving in local traffic in rush hour from Scarborough 1h40m. Long queue in priority check-in, followed by diversion from E gate entrance to D gate queues, then crossing back across airport to international gates. Travel for academic meeting has a last minute extension for university lectures, we're happy to be in person rather than online.
