British Airways has announced it is to close call centres in Glasgow and London with the loss of 400 jobs.
The Glasgow operation will close by November with the loss of 350 jobs and 50 more will go with the closure of the London site next March.
BA said it was restructuring its call centre operation because of the growing number of online bookings, and the declining number of calls handled.
Telephone calls to the airline's five call centres in the Britain have fallen by 34% over the last two years, from 13m to 8.5m a year, as the internet grows in popularity.
The airline has cut the number of staff employed in its British call centre operations from 2,300 in 2001 to 1,400 today.
The closures of the two call centres will save British Airways more than £10m (€14.83m) during the next five years.
The GMB union, which represents workers in the Glasgow call centre, described the announcement as "devastating news" and vowed to fight the closure.
