Airlines have cancelled dozens of domestic and international flights as Storm Ciara approaches the UK.
Severe weather warnings have been issued for the weekend, with strong winds of up to 80mph and widespread heavy rain expected.
Several rail firms urged passengers not to travel and said they would operate reduced timetables with speed restrictions in place on Sunday.
Ferry passengers also face disruption, as operators cancel some services.
Heathrow Airport announced it had taken the joint decision with its airline partners to "consolidate" Sunday's flight schedule in a bid to minimise the number of flights cancelled.
