THE second of two 12-hour strikes over pay and pensions has begun at Glasgow and Aberdeen airports.

It comes three days after the first of the strikes led to disruption and security delays for Glasgow Airport users.

The strikes are the result of stalled talks between the AGS Airports group and the Unite union.

Unite members at the two airports began the latest wave of industrial action at 4am and it will continue until 4pm on Monday.
