British Airways fliers face the threat of more disruption with a possible strike action by check-in staff.
Hundreds of BA workers at Heathrow Airport are taking part in a consultative pay row ballot.
The result will be known a week on Tuesday but the Mirror understands there is wide support for industrial action.
The prospect of strikes, maybe from the end of June or start of July, comes as BA has been hit by cancellations and IT problems recently. It today said 10% of its flights due to run between March and the end of October have been axed – around 16,700.
The cancellations have been blamed on staff shortages after a “fire and rehire” process that led to 9,000 workers leaving.
Customers have also reported problems trying to contact BA.
Nadine Houghton, of union GMB, said check-in staff have been abused by irate fliers.
She added: “BA is refusing to pay back the 10% cut imposed on them during the pandemic and to pay the 10% bonus other BA workers have been paid.”
An insider said instead of reinstating the cut, the company had offered a one-off 10% bonus.
The airline added: “While this is not a strike ballot, it is an extremely disappointing step.”
Boss Sean Doyle said BA was hiring 6,000 staff as parent firm IAG forecast a return to profit.
