Airport baseline
Gatwick’s check-in guidance says to confirm with the airline, while recommending that travelers reach the airport in plenty of time and at least two hours before the flight as a general baseline.
Long-haul vs short-haul
The airport notes that check-in timing differs by flight type and airline. Use the airline cutoff as the hard rule, not a generic internet number.
Add parking/shuttle time
If parking or arriving at North Terminal for a South Terminal process, include the extra ground movement before check-in.
