More strikes at airports9 Dec 2022 09:21

Home Secretary Suella Braverman said people should "think carefully" about their plans as "they may well be impacted".
Staff at six airports will stage walkouts from 23 December to Boxing Day and from 28 December to New Year's Eve.
The strikes come at one of the busiest times for travel and coincide with walkouts by train and rail workers.
It is the first Christmas since 2019 that airlines have been able to operate without widespread Covid restrictions.
Up to two million passengers are expected to arrive between 23 and 31 December at the airports where the strikes will take place, according to aviation analytics firm Cirium.
It said that more than 10,000 flights are scheduled to arrive at Heathrow, London Gatwick, Manchester, Birmingham, Cardiff and Glasgow airports during the period.
Around 1,000 Public and Commercial Services (PCS) union members - including people who work in passport control - are taking industrial action after the Home Office offered workers a 2% pay rise instead of the 10% they requested.
On Thursday, Ms Braverman said: "If they go ahead with those strikes there will be undeniable, serious disruption caused to many thousands of people who have holiday plans.
"I really want to urge people who have got plans to travel abroad to think carefully about their plans because they may well be impacted."
