Gatwick Express services will not be running throughout the week. Instead, Southern and Thameslink services will serve Gatwick Airport, offering several trains per hour between Gatwick and London/Brighton.
Services are expected to be busier than usual, particularly during peak hours.
We advise allowing extra time for travel and regularly checking journey planners.
The RMT will also be on strike on Thursday 20, Saturday 22 and Saturday 29 July. Amended timetables will run during this period, but Gatwick will have train services every day.
