Heathrow, Gatwick and more UK airports have issued a warning for passengers travelling this week, as tens of thousands of rail workers across the country go on strike.
Workers including drivers, conductors and other rail staff have launched a three-day set of strikes to push for more pay and better conditions. The action is bringing large chunks of the train network to a standstill.
The knock-on effect of the industrial action will be felt throughout the country, with many people heading off on late summer holidays from airports likely to be caught up in the disruption.
