The busiest day of the winter so far at many British airports coincides with the start of eight days of industrial action by UK border force staff at Heathrow, Gatwick, Manchester, Birmingham, Glasgow and Cardiff airports.
Members of the Public and Commercial Services (PCS) union who normally check passports will strike from 23 December until the end of the year, with the exception of 27 December. UK Border Force staff will also strike at the port of Newhaven in East Sussex on the same dates.
