The Gatwick Express train service will shut down temporarily over Christmas for essential improvement work, which will mean longer journeys for thousands of passengers during the busy festive period.
Services between London Victoria train station and Gatwick Airport will be suspended from Boxing Day until January 2.
Journey times during the closure are expected to rise from 30 minutes to more than an hour and a half.
Passengers travelling to Manchester airport from the city centre also face disruption over Christmas as there will be no direct First TransPennine Express trains from Piccadilly train station from December 23 to December 27.
