TUI has warned passengers travelling this week to 'allow extra time' for their journey in case of rail disruption.
Half of Britain's rail lines will be closed during strikes on June 21, 23 and 25 by the Rail, Maritime and Transport union (RMT). The disputes have flared over pay, jobs and conditions.
The strikes will have a heavy impact on transport to and from Gatwick Airport, with a limited number of trains running. Ahead of this week's disruption, TUI issued a statement to passengers.
